Is that really possible? if so… FUCK.
I always wondered about this when I was a kid. I wanted to know how I could possibly know that the colors I saw looked the same to me as they did to anyone else, but I just didn’t know any way to check.
My parents also used to think I was color-blind until they found out there was no such thing as yellow-green color-blind, and that I just thought it was funny to call green yellow and vice-versa.
Jesus,
I can’t read that at all.
No, this doesn’t happen. You brain doesn’t directly process the signal from each cone, it process the *difference* between signal from each cone. So if if the pigment and cones were entirely reversed, the signal difference would still be the same.
colors do not exist in nature, is our brain that make this illusion: so, there is really no way nor necessity to have a “straight” perception, it’s only a matter of difference (thank you, Matrix rebooted)
Colors do exist, in the sense of wavelengths of visible light.
As for testing for reverse trichromatism, you’d think they could reduce the green and red colors to their wavelength measurements and determine your perception of each by which “perceived” color had a shorter wavelength (red is longer than green).
Unfortunately, I don’t think most people are born able to estimate the wavelength of the color they’re looking at.
About 3.50
“So if you ever felt like there is something seriously wrong with you, like you’re not really in sync with the rest of the world, but you don’t know why or how: it may very well be because you’re a reverse trichomat.”
OR there could be nothing wrong with you at all, and you’re just like every other asshole walking the earth, yearning for a way to be interesting.
I am a beautiful snowflake, unique and beautiful and ALL THAT.
Really? Me too!

Don’t let them get to you
Don’t let them tell you
You’re all the same
Pretty colors, ‘though 😀
Everything mentioned is scientifically accurate except one. The molecules in your eyes that actually interact with the photon of light isn’t a pigment, it is a photorespondant molecule called rhodopsin. It causes a chain of chemical reactions which create an ionic environment at the cell’s membrane to shut off an electrical current down the axon (that’s right, all of sight is actually a “lack of the normal signal your brain receives”).
That’s my pedantic moment for you. Hope you’ve enjoyed.
Umm.. “No way to tell?” What about the fact that the “green light” would be at the top of the stop light and not the bottom? I think the insurance company could tell when you tried to explain why you got creamed by the Roto Rooter van.
you would be perceiving the green light as red (seeing red), but everyone always told you that colour was called green, so you would call it green.
i was thinking about how we call some colours warm and some colours cold, but wouldnt make a difference as these are things we “learn”. like the picture above, it doesnt look particularily beautiful, but if you’d learned that it was i guess it would be.
Well yes, but the addage is “Green means go.” Soo..
You’re failing at this….
Green is just the name we give the color and every one agrees on it. It wouldn’t mater what they see, everyone has always told them that grass is “green” (it could just as easily be called “bobo” or “George Harrison”) and the light is the same color, so it is also “green”
Maybe trichomats (tricromats?) know what The Colour Out of Space really looks like.
Another interesting tangent is the existence of “tetrachromats”… people who can perceive 4 wavelengths at once. Imagine how vivid that’d be.
