What does the term chroma refer to?

Chroma specifically refers to the amount or saturation of a hue in color theory. It describes how vibrant or dull a color appears. A high chroma indicates a more intense or saturated color, while a low chroma means that the color is more muted or closer to gray. This concept is crucial in fields such as art, design, and even dentistry, where understanding and manipulating color is essential for achieving desired aesthetics.

In contrast, brightness refers to how light or dark a color appears, which is a separate attribute from chroma. The combination of different hues is related to color mixing, not directly to chroma itself. Lastly, the perception of color encompasses how humans interpret colors through their vision and psychological factors, rather than the specific technical definition of chroma.
