Question

White light is incident upon a green apple. What colour does the apple appear

Answer 1

For example, a green object appears black in any other light than green (or white which contains green) because there is no green light shining on it to reflect into your eyes.

Answer 2

Answer:

The previous lesson focused on the principles of color addition. These principles govern the perceived color resulting from the mixing of different colors of light. Principles of color addition have important applications to color television, color computer monitors and on-stage lighting at the theaters. Each of these applications involves the mixing or addition of colors of light to produce a desired appearance.
