How is the color of an object determined by the brain?

256 views

I know that no object has a definite color that exist outside of the brains interpretation of the light being reflected off if an object. So if I say the ball is red what I am actually saying is in my mind I visualize the ball as red. That being said color must be a subjective experience and that color assignment is a mental activity? I would follow up to ask is it possible that different brains assign different colors to the same object? The real simple question would have been how do all humans see the same objects having the same colors? TIA ELI5

Only the name of the color is arbitration assigned. The wavelength of the light determines the color. Baring a deficiency in your eyes or optic nerves what you see as red i will see the same within a small margin of error.
