Final answer:
Saturation contributes to a color's perceived energy or vibrancy. It is true that as the purity and intensity of a color increase, so does its perceived energy.
Step-by-step explanation:
The statement that saturation of a color contributes to its energy is true. Saturation refers to the intensity or purity of a color. When a color is at its full saturation, it is at its purest form and exhibits its highest intensity. The primary colors, for example, are considered fully saturated and demonstrate the maximum intensity a color can possess. However, as colors are mixed or as white or black is added to create tints and shades, the saturation—and thereby the perceived energy—of a color can diminish. Therefore, a color's saturation can indeed contribute to the sense of energy or vibrancy it portrays.
