If you printed out the picture there would be no illusion.

Why would this be true?

They're saying screens use RGB which has no yellow, directly.

Printing uses CMYK which can print yellow, directly.

I mean even then it depends on the lighting in the room. If you have LED lightbulbs there is still no “actually yellow” light.

Also your eyes don’t care.

A printed version of the picture will still maintain the illusion. I’ve actually seen a variant of this illusion printed in a book before.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.
