Why a white fence appears to be white. In your answer include the colors of light that your eye detects and tell how your brain interprets those colors.?

A white fence appears white because it reflects all colors of light equally. When light hits the fence, the pigments on the surface absorb some light wavelengths and reflect others, creating the perception of white. Your eye detects the different wavelengths of light as colors, which are then processed by your brain to interpret the combination as white.
