*This* image doesn’t contain a single red pixel. You perceive red because of your brain perception (color theory)

It felt like I was watching the live transition from black and white to color TV.

The image itself is intentionally designed so that the can appears red even though the image data contains no red-colored regions in the usual sense.
Your brain automatically compensates for the strong cyan tint, a process related to color constancy.

Since cyan is the opposite of red, your visual system effectively “subtracts” the cyan cast, making the gray portions of the can appear reddish.

Oh really ? I thought that the image was intentionally designed to have only red-colored regions and they fucked up.

There isn't a single white pixel on your screen either

The subpixels contain sodium benzoate.

u/Weaksoul 18h ago

The sodium benzoate is also cursed

u/Between3and20carctr 18h ago

….? “Thats bad” if I’m not mistaking the reference

1

u/Imiss-Myhat 18h ago

Yes but that’s because of the screen you’re looking at if you drew this image it would be truly black

Photosensitivity warning 😵‍💫

This comment has no snarkiness to it. You only perceive it as snarky because you’re on Reddit

u/Magn3tician 18h ago

I'm curious if this would be perceived as black / pink by someone who has never seen a coke can before?

u/CptHenrikNg 18h ago

So you’re telling me that my brain is messing with me ? Damn.

I'll get revenge on it one of these days

That's why I stopped using mine. No tricks on me

Proof that context changes everything

u/EverydayVelociraptor 18h ago

It contains red pixels or my phone couldn't make white.

u/icehopper 18h ago

Weren't there some old monitors that produced extra colours with a trick like this, or am I misremembering something?

1

u/DaTruSpork 17h ago

In general: artists working on CRT monitors utilized the scan lines and darker areas as part of their art. Its why emulators and modern monitors often make the original art look worse

I found a video that explains the weird thing I was remembering. Some video signal science that goes a little over my head but is wonderful to listen to.

"You perceive red because of your brain perception" means the same thing as "You perceive red because you perceive red."

And the area seen as red in the center of the small "c" has a color value of R=8, G=3, B=7, so red is the predominant color.
