What is color? - Colm Kelleher

[@tylerhanley1409]

The graphics on this video were amazing, I love the geometric style.

[@deepshah08]

Do you know what software do they use to make it? I really wanted to know

[@Gamer-uf1kl]

Well, everyhing is geometrical but I think you meant not using curves but rather just line segments

[@cohandora]

Low poly style to be exact

[@DrJake-dl7rg]

I've a developing playlist which contains such beautiful and unique animations from ted-ed. kzbin.info/aero/PLFk0iUe0nOog6aiub6-3PXeJeArHTaEfR

I was exactly looking this information, thank you for making it so simple. Excellent video.And for all the people who are claiming that this is a bad video, consider the title. It is called "What is color?", not "How do we see color?". If you are looking for that one it is right there on the suggestion box, made by the same person. Learn how to look.

[@Aceionz]

Love the animation. Looks very professional and is, in my opinion, way better than the 2 dimensional animations seen so far in your videos. I'd love to see you keep up this kind of animations for your videos! The better the visuals, the more enjoyable and easier the learning experience is!

[@aravindnarayanan5664]

This is super impressive as all other animations but 2D is better in my opinion

[@JohnnyJackPompolla]

I loved this video, the animations were sweet and explained everything very well!

I seriously don't understand why there are people who hit the dislike button on TED-ED videos. Like, really? it's educational, why you gotta hate?

[@naautilus0]

I think they don't like school

[@naautilus0]

ur right :P

[@LittleBlacksheep1995]

The real question is, is there even anything (on youtube) that no one dislikes?

[@DanielSalasDenegri]

is just people that hate to realize that science and heavy metal is everywhere

[@iMacBoy91]

This is way more interesting and fun than the boring physics class I had when I was a kid. This is how lessons should be taught! Fairly intuitive and easy to remember.

[@johanliebert6734]

what if we all see different colours as we cant explain colours

[@dennismeng6425]

Tau I think the lastest video can tell you the answer.

[@mdsalehuddin4854]

MOLT Then that's a different question. Your question would be "How we see colours", not what

[@darkdreamer7592]

In our eyes, there is cells called cones. there is 3 type of cones. -one absorb only blue -one absorb only green -one absorb only red each type of cones absorbs specific range of spectrum. means that the first would react at electromagnetic waves that have frequencies about the blue color. the others goes the the same way. So when we say blue, it doesn't matter how we precieve it, we always referring the same electromagnetic wave. It has no use for us to argue about what we actually precieve, as long as we precieving the same thing and talking about the same thing.

[@cosinarthe5991]

Thats actually true.. we don't "see" the same colors

[@Bruh-_-911]

Oof I’m colourblind

[@isaac0621iw]

Are you kidding me?? I think this is a great video! I never understood what frequency was, and now Iv'e learned a lot more about color than i knew.

[@jiberish001]

Fun fact about "color". It comes from older words that used to mean 'a covering', 'to hide or conceal', which later became just the cover. I find that interesting that it's related to words used to describe that which prevents one from seeing the inside of something. :)

[@mariajosedelatorre4197]

Some time ago, in a Gilmore Girls episode Lorelay says that her now grown daughter asked as a child "what is color?" and i couldn't stop thinking about it, thank you for the information.

[@niker-e1e]

Color is nothing more than a description of how fast a wave of light travels. The lowest frequency is red and the highest is violet.

[@CeruleanCrumpet]

@mainlyno it's not so much that it 'should' be spelled one way or the other, but obviously people have their preferences. imo you're better off picking one or the other depending on the majority of your audience's locale. Having said all that, I agree with you -- it just looks so much fuller with a 'u'.

[@SuperTVTVTV]

What I want to know is why it reflects the colour yellow and adsorbs the rest?

[@iamjake777]

Beautiful animation!

[@andresantosid]

Pretty cool animation!

[@andyiswonderful]

The explanation that different frequencies equate to different colors is basic physics. However, the biological and psychological meaning of color is a much more interesting question, imho. What is this experience that humans have where we all interpret these different frequencies as a shared experience of "color". How are our brains creating this illusion of a colorful world?

[@Seancooke89]

His name and accent are Irish , fair play buddy ! Good video! what you studying ? Physics ? Is this video part of college or is it just a project you are doing ? I would be interested in making videos about science. Love teaching others!

[@drifter292]

[@-_Nuke_-]

God only know's how much time and effort took for this 3 m animation! It might appear easy, but it's definitely not so!

[@anishravani5808]

Just a little bit change in tiny *length* of wave creates a different *color* ∆LENGTH = ∆COLOR !!!!! THAT'S AMAZING !!!!! isn't it ?

[@kat-oh3hx]

can we talk about that amazing animation?

[@mirnalinidivakar6937]

Amazing Animator.

[@milarovas4363]

Photons don't have colors. It's our eyes (and particularly the rods and cones in our retina) which can detect the frequencies of photons at a particular spectrum which we call visible light, and send that information to the occipital lobe through our optic nerve, which we then perceive as color, but that's local to human brains. Our brains "create" color. Other brains and eyes of different animals process the EM spectrum differently. For example, bees can see ultraviolet and snakes, infrared.

[@ElQaheryProductions]

stunning graphics !!

[@bavaun6575]

2:40 Wait so how about the other colours like brown, peach and so on?

[@N0URii]

best 3 minutes video on youtube

[@drunkenmuse]

All light consists of waves, those waves are interpreted by the eye as color. By placing very small lights (Red Green Blue) very near each other (as in screens), we percieve them as 'white' together - because combined they make up our visable spectrum/'white' light. Then the R G B lights are lit up in various combinations and strengths to get the colors wanted.

[@PaulFrank_paz]

Well done.

[@VahidShirvani]

The graphic design was beautiful

[@TheFrix8]

Amazing animation!

[@snowmister2]

Visible spectrum 400-750 nanometers. Some people have a restricted visible spectrum, for example, 500-700 nanometers. This does not include the lowest and highest frequency wavelengths, which is why some people are colorblind. Great video

[@iloveSeungHyun09]

Great video. Your accent is awesome by the way.

[@11STANE11]

i have so much respect for this guy right now. metallica t-shirt :D awesome!

[@68zikriyashahid81]

I mean if you paint this yellow pencil to blue, are we changing the frequency of the light being emit? How does changing the colour actually change the frequency? Then how are colours made in the first place?

[@m10domusic]

I like the "crafty not cruddy" sort of look!

[@Flaggag]

that metallica reference was sick bro, you got it.

[@quietthomas]

We use magic crystals called phosphorescent crystals 3 kinds that emit the three primary colours of light (RGB) when they're struck with electrical charge... we used to shoot electrons in an arc at a grid of the crystals (CRT monitors) nowadays we tend more to use electrified grid layers of the three colours of crystals in very soft (almost liquid) states (known as LCD). Anyways, the colours are electrically enhanced but essentially physical in nature rather than digitally pulsed to a frequency.

[@crisvilasboas]

Pretty amazing video! It's a theory of color class!

[@smengel3]

So how do things like colored transparent glass work? When you shine white light through it, does it only allow certain wavelengths of light to pass through? If it does, shouldn't the color of the glass and the color of light that passes through it be different since the color of the glass is the light it reflects the most while the color that passes through the most would not be the most reflective?

[@GamerSawa]

If this is so how come water make the colour like red different

[@cheeseburgermonkey7104]

2:40 what if you're colorblind?

[@Hashslingingslasher-]

But WHY does the pencil reflect the yellow light more than other light?

[@renatinhuuu1]

+Hashslingingslasher because the pencil is yellow

[@Hashslingingslasher-]

+Sr Dollar i dont think ur right

[@renatinhuuu1]

***** I'm actually right, read: colors-do-exist.blogspot.com.br/2015/08/colors-exist-proof.html

[@-_Nuke_-]

Because the surface of the pencil (the rest is wood which is brown) at the molecular level is constructed in such a way, that every other frequency is absorbed and the yellow one is reflected! If you take a T-Shirt that is say red, and pour it with water, you are "filling" up some "holes" in the molecular structure of the surface of the T-Shirt. The wet red T-Shirt will (as we all know) change color! That's not magic at all, it happens because you change a little bit the molecular structure of the surface of the T-Shirt!

[@Hashslingingslasher-]

Thanks

[@madhukaragarwal598]

It actually cleared my concept

[@MedSou]

Nicely explained ,Thank you 👍👍👍👍

[@shubhamjoshi9624]

What a great video.

[@Hjerta92]

It has to do with some kind of "sensors" in your eye that can see different kinds of colors, and when some of them are "broken", you can't see that color (either at all, or not as much). I'm sure someone can explain it better than me, but that was the short version

[@frankyeboi8866]

this animator is amazing

[@TheBelmontClan]

Maybe because color is a word that represents an idea of what it is to visualize the concept of spectrum. One could imagine all kinds of different colors outside of spectrum, thats not the problem, the problem is feelings and emotions towards those colors outside the spectrum. Feelings and emotions generally function off premises of comfort rather than matter with purpose.

[@jerryh654]

I LOVE THIS KIND OF THING

[@KadenKeep]

What about how each person perceives the color differently? Is it possible that the blue that I see is a different one than the one you see? To me, that would explain why certain people like different colors better than others.

[@markoneill2447]

+Kaden Keep I've disproved this.

[@skoopysallu]

Very good video...... Superb..

[@LucaM]

The rest of the (visible) light-spectrum is absorbed by the material. Simplified this happens when the atoms in the material tend to vibrate with the same frequency as the absorbed light. Hence the atoms get stimulated to vibrate even more which manifests in rise of temperature. You can imagine this like shaking a Flexi-Bar. Shake with the "right" frequency and you get hardly any feedback from it, it seems natural. Shake in an other frequency and feel the energy beeing "reflected" into your arm.

[@hrishikesh3231]

Paint has the same constituents... y do they reflect / absorb light differently?

[@bogdanmanescu1135]

Paint has many similar constituents, but the one different ingredient that is different between paints is the one we call "pigment". The pigment is a colored substance, either naturally occuring or synthetic, which has specific molecular properties that give a certain color by specifically absorbing/reflecting certain wavelengths. You can find more information on the wikipedia page dedicated to pigments en.wikipedia.org/wiki/Pigment

[@feathertail6327]

Learned more from a three minute video, than an entire physics course.

[@anidiotttt]

@@alireardon6664 didn't teach them right.

[@unvergebeneid]

Yeah, I also found the video very simplistic and physical in nature.

[@abrahamgomez1637]

The animation is so pretty

[@drunkenmuse]

Dogs are dichromats, while humans (with 'normal'/fully functioning vision) are trichromats. It's a bit complicated to explain on so few characters but if you are interested about learning more you can always google it for more information.
