Why are most optical illusions black and white?
Why are most optical illusions black and white?
The illusion is based on chromatic adaptation. It’s basically the white balance of your brain if I can call it that way. In other words, it’s your brain’s ability to keep the colors of the scene constant even when the lighting changes.
Is color real or an illusion?
Despite the extraordinary experience of color perception, all colors are mere illusions, in the sense that, although naive people normally think that objects appear colored because they are colored, this belief is mistaken. Neither objects nor lights are colored, but colors are the result of neural processes.

If colours were simply a naming scheme for wavelengths then pink is not one, because it is made up of more than one wavelength (it’s actually a mix of red and purple light).

Do dogs see in black and white?
Dogs can see color—contrary to what we once thought. Although they don’t see in black and white, they also don’t see the same colors as humans. The anatomy of dogs’ eyes and their photoreceptors differ from that of humans (and other species), giving dogs a unique visual perspective.
