Newton observed that color is not inherent in objects. Rather, the surface of an object reflects some colors and absorbs all the others. We perceive only the reflected colors. Thus, red is not “in” an apple.

I would assume that this actually means that we live in a would without color. Color is only a perception, a function of the brains interpretation of light wavelengths, and is not real or absolute.

And do we all perceive the same colors?

Is your blue the same as mine? Is it my red?
