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. The surface of the apple is reflecting the wavelengths we see as red and absorbing all the rest. An object appears white when it reflects all wavelengths and black when it absorbs them all.

We know we are seeing the same thing, because we have measured the different wavelengths of colors, and we all agree to call the wavelength of an apple, for example, red.
CityBoyGoneCountry Reviewed by CityBoyGoneCountry on . What are the senses? If you see a shape that is the color red, any child with the basic schooling will know it is the color red. But is the color red that you see the same color that i see? If my brain was to look through your eyes would the color I see be red or another color? If someone tells you a color is something that is what you will know it to be. What if when you see blue, i see green. But since we were told all of our lives these were the color red that is what we would believe it to be. Rating: 5
