Which term defines the dimension of color that describes its intensity?

Chroma is the term that defines the dimension of color relating to its intensity. It describes how pure or saturated a color is compared to a neutral gray at the same brightness level. A color with high chroma appears vibrant and intense, while a color with low chroma appears more muted or closer to gray. This concept is critical in color theory because it helps artists and designers understand how to manipulate color for different effects.

Hue refers to the color itself—whether it's red, blue, green, etc. Tonal value relates to the lightness or darkness of a color, indicating its brightness level regardless of the hue. Balance refers to the distribution of visual weight in design and does not pertain to color intensity. Recognizing the distinct meanings of these terms is essential in the study of color theory in architecture and design contexts.
