Color II

Try it: Surface reflections and saturation.

To see the effects of surface reflections on the saturation of colors, examine a shiny red apple or a piece of colored plastic in a room with several lights.

Notice that no matter how intense the red of the apple, or how saturated the color of the plastic, the highlights (surface reflections of the lights) still appear white - completely unsaturated.

View the apple outside on an overcast day, when there are no highligts. Does this affect the saturation?

Crumple a piece of colored paper and compare the saturation of a part of the paper that is partially shaded with an adjacent part that is not.
