Which color characteristic measures the strength or dullness of a hue?

The strength or dullness of a hue is referred to as intensity. Intensity describes how vivid or muted a color appears. A high-intensity color is bright and pure, while a low-intensity color appears more subdued or grayish. This characteristic is crucial in various fields, including art and design, as it helps to create visual interest and harmony in compositions. Understanding intensity allows one to manipulate colors effectively to achieve desired emotional responses or visual effects in their work.

The other characteristics—hue, value, and temperature—serve different roles in color theory. Hue refers to the specific color itself (like red, blue, or yellow), value measures the lightness or darkness of a color, and temperature denotes the warmth or coolness of a color. Each of these aspects contributes to color perception but does not address the strength or dullness directly, which is the essence of intensity.
