What does "intensity" refer to in terms of color?

Intensity in terms of color specifically refers to the brightness or dullness of a color. It measures the saturation or purity of a color, indicating how vivid or muted the color appears. A color with high intensity is bright and vivid, while a color with low intensity appears more gray or washed out. This concept is crucial in visual arts as it helps artists create depth and focus within their compositions. Understanding intensity enables artists to manipulate emotions and make certain elements of their artwork stand out through the careful selection of hues and their saturation levels.
