So would it be fair to assume that this is why our eyes have adapted to use green light as an indication of brightness?

Would you happen to know if this is why most photosynthetic organisms on earth are green?

[@valrond]

Gratz man, you deserve it. I had never thought you could do so many cool things with Universe sandbox 2.

[@angushuynh2127]

lol mixing equal amounts of rbg turning white only applies to light, whereas paint would make brown, purple or black depending on the paint medium

[@whatdamath]

good point

[@jamest.5001]

angus huynh mostly what I got was brown to pink. depending on the amounts of what colours.

[@rehakmate]

yep

[@IAmAlgolei]

Yes, paint pigments ABSORB light, so when you mix red+blue+green you combine their ABSORPTION properties and the paints appear darker. If you mix things that EMIT red+blue+green light then you would combine their EMISSION properties and the result would appear whiter.

[@BresciGaetano]

if u balance pigments nearly perfectly to 1/3 each yellow/cyan/magenta you actually get a gray same as mixing 50%-50% withe-black. It can turn different depending on medium or the glue and solvent the actual paint use or chemical interaction between pigments.

[@gavinfunk7362]

What about Purple stars?

[@Tuxy-22]

i have seen a purple star in space engine before

[@adventurerben9006]

They are almost certainly possible, but they would have REALLY short lifespans, I imagine that they would have been the first stars in the universe with really tiny lifespans of maybe a million years or less.

[@gavinfunk7362]

AdventurerBen The Pro Cool!! Thanks for the info!! I was just wondering

[@hugoyu2001]

I think if you are going to have purple stars you need them to be very hot to not have any blue light and just purple light and other invisible spectrums. In that case, I think it will last even less than a few million years. They should only last less than 100 thousand years as I’ve heard some blue hyper giants are already at 100 thousand years lifespan. So good luck trying to spot them before they die.

[@767track9]

[@williamdaliege1016]

There is one: Beta Librae (Zubeneschamali) is the only naked-eye green star; reported as such throughout history. There's no settled explanation as to why people see it as green, but they do. I pointed this out to author Marshal Savage (via a brief but pleasant e-mail correspondence) many years ago after reading his book 'The Millennial Project: Colonizing the Galaxy in Eight Easy Steps' , where he suggested (with a nod to Freeman Dyson) that green stars might indicate living habitats around them (he, too, had not heard of Zubeneschamali). I have wondered ever since if SETI has ever aimed their radio antennae toward Beta Librae's direction.

[@G3rain1]

To rephrase what he said. All stars emit a broad spectrum of light in a sort of bell curve distribution. Where this curve peeks determines the color. Because green lies in the middle of the visible spectrum, when the peek is green it also means the star is emitting large amounts of blue and red light, so it appears white. Because red and blue sit on the ends of the visible spectrum it's possible to get mostly blue or mostly red stars, because if the peek of the curve is blue or red a good portion of the curve will then sit outside the visible spectrum.

[@hahahadracula]

Im pretty sure that if you combine red, blue and green paint it will become dark brown. paint and light don't work the same way, painting is subtractive light is an additive.

[@BaconTheRabbit0]

hahahadracula I think he confused traditional painting with a digital painting program which would follow the RGB colour system.

[@hahahadracula]

BaconTheRabbit I know but he made it sound like he was talking about paint

[@happytiger624]

Anton already make a video about that

[@ulfmoren3334]

Berts värd

[@Thumper770]

Light is only additive if it's being emitted. Reflected light is subtractive. A black piece of paper appears black because no color (or light) is being reflected. You can make red paint look white under a red light source or through a red lense.

[@peterpzazz2441]

An analogy to star colours & temperatures could be seen in a foundary. Heated metals glow from red to almost white as their temperature increases until they melt but never glow green.

[@BDKITCHEN2012]

😂

[@pbrower2a1]

Technically -- if you mix pigments, you do not get white. Mix complementary colors such as yellow and purple, red and green, or blue and orange as pigments and you will get something nearly black. Mix colors of light, and you get brighter light. The sun emits largely green light, but green is close to the middle of the segment of the electromagnetic spectrum known as "visible light". It's the mixture of light that is white. But use a prism to divide the visible light from the Sun, and you will find a green component from the light. Another angle: the photosynthesis by algae, ferns, and leafy plants relies heavily upon the reddish light in the visual spectrum, as the plants absorb the warmer, reddish light for breaking down water but cast off the bluer shades of light. Plants are green because they reflect what the plants do not absorb. The light that plants reflect is largely the yellow-to-blue shades of sunlight. which may be a better explanation of why the sun is really a 'green' star than any direct observation.

[@darkonc2]

When peddling in red, the low end is infra red. When peaking in blue, high end is lost in ultra violet. When peaking in green, you get lots of colors everywhere [I. E. White].

[@Sneaky1ne]

Anton you don't get white if you mix paint, you get an ugly color dark brownish or green not unlike poop.

[@adamas_dragon]

Sneaky1ne That's what I thought, that only works with light spectrums not colours

[@aomafura3374]

That's different because some pigments/coloring materials don't mix well with other colors. Instead try this, have a piece of hard white paper and divide it to 3 parts. Color each parts Red, Blue and Yellow. Spin the circle really fast and you will see white.

[@chrisjohnson8666]

Ao Sama, you see white from the mix of blue, red and yellow patches on the colour circle as the circle spins. With paint it is different, it only reflects its colour and absorbs the other parts of the spectrum. Hence Sneaky1ne is correct, mixing these colours produces a brownish colour. It would be black only with one specific mix of colours.

[@tabularasa0606]

There's a difference between additive color mixing and subtractive color mixing. If you mix paints you do subtractive mixing. If you mix light you do additive mixing.

[@charlieevergreen3514]

+tabularasa0606 Exactly. I also explain this as emitted light/color vs. absorbed light/color. If you're playing with colored light, you control what's emitted. If you're playing with paint, you're controlling what's absorbed.

[@I.amthatrealJuan]

It is the reason why no hot objects glow green. It is not only exclusive to stars.

Thank you for your videos. It makes it easier to learn about this kind of stuff decades after my last Earth Science class.

[@AfromanSkeeter]

Additive vs subtractive color explains the mixing of light vs mixing of things like paint and the different result you will get.

[@vovacat1797]

So what you were basicly trying to say that our sun peaks at visible light? Doesn't it mean then that this exact narrow part of the spectrum is "visible" just because you get more light in it during the day so evolution works to make it nost useful? I think if we evolved under a red star our "visible" spectrum would be more into infrared. So what we call "red" would be "white" for us.

[@tomfoolery5680]

I'm pretty sure red, yellow, and blue paint mixed together isn't white.

[@vovacat1797]

Tom Foolery It isn't because when you have a spinning disc (when it actually makes white) you add colours to one another. But when you mix paints, you "subtract" them, which is like watching through several coloured lenses, because each of them lets through one colour, but significantly reduces others.

[@governmentcheese411]

no sir, our sun releases a relatively full spectrum of light, period. our eyes perceive a large portion of this spectrum. such as the red, green and yellow spectrums. but do not perceive others like the infrared or ultraviolet spectrums. this is true for stars similar to our own. a larger hotter star would be more towards the blue spectrum. because it's hotter temps don't release nearly as much of the red spectrum of light. google "images of the sun in different color spectrums". very beautiful images. and a good example also... take 3 similar flashlights and some red, green and yellow film. put each color film over a flashlight lens. and shine all three at the same spot on a dark wall. the spot on the wall will be white :)

[@imienazwisko6527]

Владимир Кузнецов Visible light is visible beacuse it's good at penetrating water, which is the substance our eyes developed in.

[@governmentcheese411]

um... no.... not even close man. jeez why would you bother commenting on what you know nothing about. first off, that is not water in your eye. "The center of the eye is filled with a jelly-like substance called “vitreous.” this substance is very thick with a consistency somewhat like “Jell-o”. the REAL reason we see the so-called visible spectrum of light. is simply due to evolutionary efficiency. to evolve an eye capable of seeing just the infrared spectrum alone. we'd need to double up on the entire eye system. and this wouldn't work on its own either. infrared vision begins to fail in high light and high heat situations. thus we'd need and even bigger eye system to include visible light. and this holds true for the ultraviolet spectrum as well. so in short, evolution chose the most efficient spectrums to achieve the most advantageous results, period.

[@imcmart6037]

If a star got hot enough could it become "non visible" because it would only emit UV light?

[@hugoyu2001]

I'm Cmart It needs to be very hot for this to happen and by the time it gets hot enough to stop emitting blue light, it should be emitting gamma rays and ranging to UV. They are however incredibly rare as more heat means it requires more mass and also it won’t last very long as it will burn up their fuel very quickly.

[@imienazwisko6527]

I'm Cmart There's alaways some light in lower frequencies, so there's always some visible light. And also every frequency get's more intense, so the star get's brighter and brighter and brighter...

[@imcmart6037]

Noel Washington and Space Dust thanks for the information and not trolling! Nice to see a comment section without trolls on KZbin.

[@magpie7791]

I don't think so IR is linked to heat,;the hotter the more I given off? But I could be totally wrong.

[@Euruzilys]

Edward straka What you are thinking about is blackbody radiation. Objects will emit radiation according to their temperature. Most objects in our everyday life only emit infrared since its not that hot. As it gets hotter, it emits more powerful and shorter wavelength radiation. A hot piece of metal glows in red wavelength.

[@StormsparkPegasus]

Basically, for it to be green, the majority of the light emitted has to be in the visible spectrum. When the majority of the light emitted is in the visible spectrum, it appears white (because the entire visible spectrum is emitted at once). If you shift toward lower frequencies, a lot of it shifts towards the infrared (which we can't see), leaving the peak in red or orange. If you shift toward higher frequences, a lot of it shifts towards the ultraviolet (which we also can't see), leaving the peak in blue.

[@ryanheeren3781]

I wish purple star exists

[@BirdBrained18]

Ryan Heeren They do, but our eyes aren't sensitive enough to detect them.

[@demonslayer6267]

they do, but our eyes pick up blue more then they pick up purple so they would look blue to us

[@thesentientneuron6550]

Demonslayer This is actually very true. In fact, our sky is actually quite purple, more than it is blue. However, the fact that our eyes perceive blue more sensitively than purple makes us perceive a blue sky and not a purple one.

[@Madplanetguy]

Ryan Heeren they do, they are colder blue stars

[@thesentientneuron6550]

Madplanetguy 2004 No, purple light is at a higher frequency than blue. And the hotter a star, the higher the frequency of light it mainly emits. So not colder, but hotter

[@fuhue5945]

Anton Petrov, your channel taught me many things about astronomy and it's better than school.

[@jaredjordan9863]

Our Sun appears white from space, but yellow from Earth. This is because our atmosphere most strongly scatters blue light, so the light from the Sun reaching our eyes has a significant amount of blue removed.

[@erickarevalo9158]

Exactly, ozone layer filters and disperse the blue light onto the armosphere so that's a technical explanation

[@kittenmitten2948]

[@silentgamer3419]

[@ThrottleKitty]

I'm pretty sure green stars are quite possible! I remember seeing a thing a while back about stars pre-supernova burning "contaminated" non hydrogen/helium metals resulting in spectacular colors. So just need the specific contamination for green (Argon?) in a star that's large enough at the exact right dying breath!

[@NEnigma777]

Wrong. Argon has nothing to do with it. It all has to do with the cones in our eyes and how we interpret color. We will never be able to see a star as green because where it falls on the spectrum. We will see it as white

[@brian554xx]

short answer: blackbody radiation with a peak frequency in the center of our visual range _is_ green, but luminosity across our whole visual range is high enough to desaturate it to white.

[@cooperfeld]

@Mark Mozer: All paint colors mix to black, all light colors mix to white. KillerDempsey115 got it right - he was referring to what the guy in the video said. He talked about painting in elementary school - assuming they still use real paper and paint there instead of "photoshop" ;).

[@paavobergmann4920]

technically, you get something like dark olive drab, as no pigment is perfect.

[@Nixie-Nix]

quickest known explanation possibly our eyes pick up color lengths, known as primary and secondary lengths. I'm excluding tertiary lengths from this. the primary colors are red, blue, and yellow. the secondary colors are orange, green, and purple. secondary colors are made by mixing two colors together. for example, you get orange by mixing red and yellow. so, to put this short, our eyes perceive the primary colors over the secondary colors. the secondary colors don't necessarily exist, they're the result of our eyes perceiving more than one color wave length at a time. a green star could only exist if our eyes perceived green on its own. however, they don't, because green doesn't necessarily exist. rather, it's a co product of existing colors, and those existing colors don't mix into one another in space. there's no such thing as a red star with a blue hue or vice versa. it's based on temperature. so in short, green stars don't exist because the primary colors, the only colors in space, don't mix with each other whatsoever, therefore secondary colors don't exist in space.

[@berndpfe]

The only possibility to see "green" stars , might be some few with the necessary dose of "doppler-shift", when flying away from our perspective. So the right speed, resulting in a maximum in the "green" spectrum will make a blue star appearing indeed green. But there seem to be almost no stars exactly showing this feature. Some distant galaxies appear somehow greenish.

[@lanedexter6303]

[@OmegaVideoGameGod]

🤣

[@fajita2]

5:25...actually if you mix all colors in painting you don't get white, you get a brownish color. It's the same concept with light, but paint and light are not really analogous, so it still makes sense that light becomes a bright white when mixed together.

[@ezskillz2004]

Do a video on why do stars turn red in their last stages of life if they are not cold like red dwarfs

[@briantorrey01]

They are cold llke red dwarfs in a sense (at least the surface is).. When the sun expands and becomes a red giant toward the end of its life the surface temperature. decreases. while the core temperature increases. By the time the light gets to the surface of a bloated star that has long ago gone of the main sequence it is travelling through and is therefore being emitted by relatively cool super heated gases at the surface. the surface temperature of betelgeuse is 3500k which is low on the Hertzsprung-Russell diagram

[@AleronWolf]

I know it has been said, but still, paint and light mixes differently. And you use different colour schemes for both. Light in RGB usually, and paint you'd use CMYK, if I recall it right.

Thomas Bob I'm saying the truth

[@ThomasBob]

Crunchy Toothpick No, that's an opinion

[@Midaspl]

Technically there should be few ways to make a green star. It's just not exactly the star that would be emitting it. The simpliest would be that the star could have some kind of gas gathered around it that would filter the light, passing only green, or small particles making a green refraction to the earth. I think there are nebulas that appear green, so it would be basically simmilar thing. Other way I could think about is redshifting, although it's theoretical and I'm not sure if anything like that exists. If you take a look at the graph at 3:50 , the hotter the star is, the higher is the peak of emmited light and the more steep the curve is, so if you took a very, very hot star that emits mostly just UV light and make it fly quickly away from us, at certain speed it should appear mostly white, but due to the difference between peak value and rest of the curve, it should have a green tint to it.

[@jackmortimer329]

This looks like the same color spectrum a black smith sees when heating iron in his forge. I think he never sees his metal being green.

[@rebelbeammasterx8472]

Is there a hypothetical way to make a green star or purple star?

[@icedragonaftermath]

RebelBeamMaster X84 Only if we could manage some major engineering projects. But first, why things look the way they do. Now, stars emit a mix of all the lower frequency wavelengths of light associated with a given level of energy. Now the lowest frequency color of light we can observe as humans is red. Anyway, the first visible color we can see is red. The second is green. Now, when the brightness of red and green light is equal we see varying shades of yellow color. The third is blue. When red, green, and blue lights appear equally bright we actually get more of a blue-white light. So for stars we mostly just transition from red -> yellow -> blue-white as we check more of the check-boxes for what color receptors in our eyes get activated and at what intensity. You can also see this in most fires, unless you add certain chemicals to it with very specific emission values. Now, if we want to change the color of a star there are a few ways we can do it. Placing a large filter around a yellow or white star would allow one to selective absorb non-green light. It should involving building a structure that completely surrounds the star though, making it physical larger quite larger than said star with a very unstable orbit. This would either require constant correction or end inthis immense sphere colliding with the star and being torn, shattered, and vaporized. Basically, fun all around. Alternatively, we could try to somehow engineer a star containing elements that primarily emit green light, much like how one can burn copper to create green flames. The only issue is, stars that are mostly tend to have heavy materials such as copper located towards their cores, not the surface of the star. While we could surround the star in a cloud of copper, when it heats up after hitting the star's "surface" that star would appear green for a brief instance, which isn't particularly satisfying.

[@kasey42]

Sure, if you had a star fusing mostly copper...though this is not theoretically possible, it is a way for a star to glow green.

It was great, but maybe it is also worth mentioning that the light of the Sun is not "accidentally" white, but our eyes evolved the way that objects reflecting the full spectrum of sunlight getting us no colour information: means white. If we had evolved at Betelgeuse (which is a red giant) we saw the Betelgeuse as white, and we saw our sun at the distance as blue (means: more blueish than Betelgeuse).

Problem with color apectrum is that our atmosphere changes the true color spectrum of the universe. Having Hubble will help alot. Violet light aka purple is much lighter than blue shades. Green gets separated because of prisms. You will see neon yellow much more often or see sunburnt orange as well. And because stars burn, chemicals burn at different at different rates. Red has the biggest light wave.

"If your've ever done painting at school", you will notice when you mix all the colors together, they form black. This is called subtractive color, such as CMYK, and what the speaker is trying to say is when you use additive colours such as RGB, such as filtered light, you get white, certainly nothing to do with painting, unless u mean the program Paint, which is RGB hence additive colors, think LCD screens.

[@erictaylor5462]

Well, there is yellow snow, but you should never eat yellow snow.

[@theroyalgaxaly9773]

????????????????????????

[@erictaylor5462]

I take it you are not from a place that gets snow?

[@luongmaihunggia]

Eric Taylor yellow snow = dog pee

[@erictaylor5462]

Yellow show MAY be dog pee, but it may also be other kinds of pee. Deer pee, cat pee, hell even zebra pee is possible. Or it may just be food coloring.

[@luongmaihunggia]

Eric Taylor if it is food coloring than it's ok to eat it

A theoretical "black body" is a perfect emitter of heat/light as well as a perfect absorber of heat/light. The peak radiation power from the sun is at around 500nm, 500nm wavelength, which is green.

Because green is not a creative color

[@Elliandr]

A green star isn't impossible, it just requires a rather specific composition that has never been observed. Doesn't mean that one doesn't exist, but if one ever did it would be so rare we'd probably never see it.

[@gabrielrej834]

tl;dr Stars don't just emit red light or just green light, or just blue light. Instead they emit a range of colors around their main color. So if you see a red star, it means it's mostly emiting red light, but also some infrared, some green and a bit of blue. Same with blue stars -- they emit mostly blue, some purple, some ultraviolet, some green and a bit of red. Color green just happens to be right in the middle of the visible light spectrum. Therefore, a "green" star would emit green light and then a range of colors around it that just happen to cover entire visible light spectrum, so when added together, those colors emited by a "green" star add up to color white.

[@GreenLegion]

Green isnt a primary color

Our atmosphere soaks all the green up.

[@NathanOkun]

The reason is that our eye-brain decoding system for blackbody radiation curve that matches the Sun gives white is that if it did not and gave a green color, then we would not be able to see green in grass or leaves or anything else (green-glowing-light-on-green-reflective-objects is colorless). If the color green is shown by itself as a glowing object, then you DO see green (copper salts in a Bunsen burner blame, for example), because there is so much green light that it causes our blackbody-curve internal logic to be turned off (it is not Sunlight) and ALL colors are now visible individually. This special logic in our brain, which we cannot bypass without destroying our color vision almost completely, is why glowing colors and reflective colors have to use different color wheels (reflective colors allow green from mixing blue and yellow, for example, which does NOT work with our eyes with glowing colors).

Sam john are you three years old?

[@hypertion]

why yes! i did do painting in elementry school, and i always got black or more commonly various shades of brown or deeeeeeep olive green! lol, pigment mixing vs light mixing. they operate exactly opposite of each other. Pigments block a light, and having pigment of each light blocks all light creating black or a minimal reflective surface. meanwhile with lights themselves, they are the light. white is the result of of all colors mixed when concerning light sources because white is simply the entire EM spectrum at once. so mixing pigment blocks all of the spectrum, producing darker colors or black while mixing different spectrum of light create the combined result of those lights, producing brighter colors or relative white. one subtracts as more is added, the other adds what is added. on a fun side note, and a little curiosity.. i wonder if the reason why most plants are green, if our sun peaks in the EM output in that range.

[@Shaden0040]

There are green stars Sol is classified as a yellow-green star.

[@Jacob-bi1oq]

Sol is classified as a white main sequence. Not sure where you heard that

[@Shaden0040]

Maybe in the classifications you've seen. I've seen different.

[@renepadilla7104]

Shaden0040 so is a type G2V yellow dwarf star. Easily confirmed by searching NASA, esa, and many other sources such as Harvard

[@crackedemerald4930]

Rene' Padilla or looking at it

[@Jacob-bi1oq]

Shaden0040, the sun is every color but white

[@skaterfugater]

the primary colors are magenta (pink-reddish), cyan (blue-turqoise) and yellow. Hence cmyk. if you mix those you get a dark brown. a perfect black cannot be achieved, nor can something "colorless" such as grey. creating white from rgb lightwaves is something different. physical colors dont work like that. for instance, with physical paint blue and yellow equate to green, red and yellow to orange, blue and red to purple. if you mix red green blue (rgb) with physical paint like in arts class or elementary school, you simply get a blueish brown. rgb pixels work differently than mixed color pigments.

[@smallblue08]

There is no green stars because you haveny collected all the original power stars smh.

[@MrCubFan415]

I get it! (It's a Super Mario Galaxy 2 reference.)

[@구독자500명되면이같은]

In black bkdy radiation curve when peak wavelength is in green range, itd emit a lot of light in red and blue ranges also. So itd appear white

In anime there are colorful stars ;)

[@Jnvmar]

because it wants to be here

[@madscientistshusta]

Its because of the nature of light since green is essentially the center of the light spectrum we have evolved our eyes to utilize center spectrum light as white light white=green. The issue arises when you derives light from tempature like we do from stars, you get green but you also get equal parts red and blue. If you take a photo color filter and mix red green blue it will come out white. A star cant be green because green comes at the price of blue and red. That is the nature of colors from tempature or the light spectrum

Stars are only available in selected colors from the Kelvin color scale chart. See store for details. Hydrogen sold separately.

[@rvaughan74]

Hmm, that's a nice coincidence that the Sun is a G type star. Which lands on Green in ROYGBIV which is centered enough for the light to appear white to us. Hell of a coincidence.

[@myessyallyahamericus8405]

Its yellow green. Opposite of blue green contrasting hue dudes to the earth's color look at neptunes atmospheric earth tones. Neptune is a super ice earth. If it were at earth's orbit habitable zone it would look like a blue green jupiter with massive storms and maybe 40 percent larger in volume at the same mass. Jupiter wouldn't expand because it's already way hotter than earth by it's own internal heat factory. Our sons Corona is blueish all the way to earthspathcentral. From Pluto you still see yellow dominate because of its inner Corona. Its oxygen and nitrogen and silicone gas and actual algae like critters in the vapor belt between earth and Mars but 99 percent closer to Mars than earth. Where water can float as liquid droplets. Right where hydrogen and oxygen are able to bond on nano scale

[@Jeffrey314159]

So there are green stars, spectral type F, but you just don't see the green 'cause its masked by other colors to produce white light? With red stars, spectral type M, would look white with a reddish tinge - especially around the edges(or perimeter)?

[@NicolasLezcanopy]

If you mix all primary colours: red, blue and green then you'll get black, or dark brown/grey, not white! paint works opposite to light emission, they absorb light, reflects certain frequencies giving the appearance of "colours"... To make white paint we use mainly titanium oxide or calcium oxide diluted in a medium, they're white powders. In colour theory and arts the primary colours are red, blue and yellow, green is a mix of yellow and blue! that's crazy, right? Maybe that also explains why we don't see (bright) green stars like lemon colour or something, absorption works in a opposite way as emission and to get green you need blue and yellow, the colour we do see in most stars and red is a primary colour so yeah, red stars everywhere! can't explain it properly yet because I don't really understand light emission, but it's just an idea out of arts and light absorption/reflection. Nice video btw! I like your videos because you make good questions and give great answers to them!

Orbiting a red star would be so cool! You know how everything looks more red during a sunset? Well that’s how it would look mid-day. *AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!*

[@PixlRainbow]

So basically.... Light emitted by stars follows an approximately normal distribution? At lower temperatures, the mean is closer to red spectrum, which means half the distributed light is outside the visible spectrum and the other half is mostly inside the reddish part of the visible spectrum. When the mean is around green, most of the distribution lies within the whole visible spectrum and results in a perceived colour of white. When the mean is around blue, half of the distribution is inside the bluish part of visible light and the other half isn't visible, so we see blue?

If the snow is yellow, you didn't watch out for where the Huskies go.

[@bobfree]

Blue/UV hot stars moving away from us fast would "red"-shift to green. Unfortunately, red stars moving towards us fast wouldn't have much time blue-shifting to green as they would pass us relatively quickly.

[@SailorBarsoom]

I didn't really consider why there weren't green stars until I read a planetary romance set on a planet orbiting a green star. But, the hero only sees the star when he is in astral form; the planet is too overcast for him to see it when he has a body. So, I assume that the star only looks green because he is in astral form.
