When you mix red and green, what do you get? White light is all of the colors, right? So, how do computer screens show you every wavelength of light? Or do they?

It is interest to think, red and green light make us see yellow, but actual yellow light (split from a prism for example) also stimulates our red and green cones the same way and makes us see yellow, so you can't actually tell whether you are "seeing" yellow or red and green light together (unless you can get close enough to make out individual pigment cells like in a screen). For example is a banana reflecting actual yellow light or red and green light together, you can't know unless you know what the actual pigments are in a banana.

For best results on the red/cyan effect at 3:30, watch in HD at 60fps. I promise I didn't forget to edit in the red or the cyan frames. They're there.

[@nidodson]

It gets so much stranger with impossible colors, where the brain ends up not merging them to white, but instead mixes them in a completely different way.

[@stoferb876]

Violet, or purple is interesting, because the red cones in your eyes have a little extra bump of sensitivity in the near ultraviolet range too aswell as in the yellow-red range. That's why blue and red mixed together appear as purple even though if it was using the same brain-calculations and that extra bump of sensitivty wasn't there it would have appeared as green instead.

What are you talking about? I hope you do know there are other languages? And if you have a problem with that you should leave the internet

[@HEXFILMS]

L lol ik, but not in English

[@garyperkovac1002]

Thanks, Physics Girl.... As an artist, I knew that pigment is different than light. But.., your explanation gave me the "Why".... And that "Why" is truly remarkable.... Thanks, again.

[@rajmore2104]

1:13 colour mixing and lighting mixing is different.hence cmky to print and rgb tk display

[@flozra_mhr]

I saw gray when you swap red and blue quickly.

[@flozra_mhr]

Beyza0328 111 Thank you very much. :)

[@ladwarcoffee]

when I was at 720 all I seen was bright red. I changed to 1080 and seen light blue.

[@huycao9788]

Beyza0328 111 I wonder if this has to do with the speed capability of our graphics card/display. 1080 has to draw more pixels than 720, so it's harder for the display system to keep up. Both 1080 and 720 looks gray to me; probably because my system is slower than yours. Don't know...just a guess.

[@Dhy355]

The gap between the changes makes an absence of stimulus in the cone which is interpreted as dark: dark+white=grey.

[@derlinclaire1778]

I saw grey too,friend.

[@tacksforsnacks5035]

Did anyone else see the yellow lines on the spinny thingy?

[@KealiRae]

Yes

[@randomness3365]

Im not in that list :)

[@MrAsacre123]

same here. something tells me she's got something wrong.

[@MrAsacre123]

+Lord GabeN even when I watch this a at 1080 60p

[@benedixtify]

It's cool realizing the thing with paint colors absorbing vs light beams combining

[@PeoplelyPerson]

i could watch this video so many times and never get bored of it.

[@nahjahstephen8081]

has this ever happen to you... when it is sunny outside then you closed your eyes for a long time then you open them and everything looks blueish or tinted blue ..

[@mahkari622]

Yea it happens whenever I go outside in summer and stay out there for a bit ;-;

[@bookmilla8616]

Yeah, all the time. And then it takes like 2 min to go back to normal.

[@angelcupcakes4647]

yep, happens a lot to me

[@sdx9621]

Yeh

[@jennifergrosse8646]

Yes

[@Ja.leiiii]

what all i saw was red ?

[@shelbyelana9433]

Put it on 720p60

[@nfsjoey]

It just made Pink

[@alleen52]

+Im Done Just Done OMG IT WORKED

[@shelbythelovelyneko4337]

Same... only red.

[@pitapear6656]

If u r on mobile it doesn't work

[@everything3418]

OH WOOOOOW !!! THAT'S REALLY INCREDIBLE. U ALWAYS SURPRISE US BY MAKING SCIENCE FUN :D YOU ARE THE PHYSICS QUEEN 👑

[@jimbeam4736]

Looking at those colours does domething for my brain that I cannot describe. It stimulates emotional sensations that are not connected to anything but those colours. Very nice - I love colours.

[@cameron2788]

there should be an epilepsy warning in this video

[@swedneck]

+Cameron Swaglord Yeah if there's anything that can trigger epilepsy it's gonna be this.

[@iCanHasRandomness]

+Tim Stahel (Moustached Viking) even for such a short clip?

[@georgecataloni4720]

It didn't make my head hurt like that Pokemon episode, so probably not a big deal.

[@iCanHasRandomness]

George Cataloni yeah, that's what I thought too. It's too short to do any damage, IMHO (but I'm not a doctor)

[@TehBurek]

+Cameron Swaglord I was just thinking the same thing, some "WARNING! Flashing colors incoming!" annotation alongiside 60 fps notice would suffice.

[@kaitlynwatkins2362]

It wasn't flashing.. It was just red......?

[@jordanpool9072]

Kaitlyn Watkins same

[@mayoman2674]

Kaitlyn Watkins same

[@mrskitkats]

Kaitlyn Watkins Change it to 720 quality

[@antronixxszn7215]

Change quality to 720p60

[@rholord]

TheEmeraldMiners // TEM WOAH HOW THE FUK DOES THAT HAPPEN???

[@Lettuce-and-Tomatoes]

I know better now! 😁 Thanks, Dianna!!!

[@Clearlight201]

so is the relationship between the light color wheel and the paint color wheel similar to a photographic negative? ie each segment has it's inverse on the other wheel, one depending on what light is absorbed and the other on what is reflected? my physics studies were a long time ago, so I can't recall if there's a simple answer to this.

[@WillowMistrider]

3:32 I see red O.O

[@kiraramu]

set it to 60fps

[@BnyxDaReaper]

+Florencia Colombo Blanco how

[@nataliadelossantos8062]

me too O.O

[@imaginingrainbow3039]

Same but I'm on computer and it may not work on ipad

[@cashiernumber1760]

+Imagining Rainbow I saw white am I special

[@KyleBarrf]

So is that why that whole Blue / Gold dress thing happened?

[@JayDaMane59]

It's because of the lighting in the picture that tricked your eyes.

[@OreoKit3]

Slightly different. That had to do with how your eye perceived the lighting of the picture. It would adjust as it saw fit(you see the picture is deceiving because it has both really bright yellow areas and really dark purple areas) and the result would be messing with your perception of the color.

[@tomdekler9280]

It's somewhat related. In a room lit by a slightly blue tinted lamp, your brain can contextually tell you what objects in that room are red or yellow or blue. Same goes for a room with a bulb that is tinted yellow, which is fairly common in any household. I'm looking at a rainbow-colored artwork on my wall right now by the light of a yellow lightbulb and I can easily identify all the colors, even when some would look less orange/yellow to me in the broad daylight. In that dress picture, you can't see the context. You don't know if the room is light or dark. Ergo, your brain can look at it either way.

[@loganguerra5076]

thats a year old the new trend is...

[@angelynebaker8433]

Asapscience made a video explaining the blue/gold dress thing if your interested in knowing how that happened.

[@Orthaluminox]

I only figured this out just before you said it because of the sun shining on the top at one point it looked yellow and wasnt even moving. Figured it had to do with the sun then boom light! So cool! So glad I subscribed! XD

[@doreenvalentine6361]

In graphic arts we refer to these differences as "transmitted" and "reflected" light. We scan to digital using transmitted light (red, green, blue) and print on a paper in reflective color (y,m,c,k).

[@gwenissooooocool]

no I saw grey

[@akidoesrandomthings9125]

Me too!

[@aceclown9316]

Gwen MSP and MORE! me three

[@Timo3timo]

good thing I have epilepsy

[@ilprincipe8094]

xDD

[@kennyvx5914]

+ilPrincipe I don't get it

[@briannaspaghetti5117]

The flashing screen.

[@wesremy]

Hahaha

[@lextonravaee3490]

+spooky hacker it's a condition where flashing colors can make you have a seizure and it's just a joke you're obviously dumb. Jk a lot of people don't know

[@stephencech3696]

Your enthusiasm makes this channel extra special! I learn stuff (what I thought I knew) every video I watch, and I will never be able to thank you enough!

[@carchub]

Wow thanks this was awesome!
