What are hue value and chroma in painting?

In painting, hue refers to the actual color itself, such as red, blue, or yellow, representing its position on the color wheel. Value indicates the lightness or darkness of a color, which can affect the overall mood and depth of a painting. Chroma describes the intensity or purity of a color, with higher chroma having more vividness and lower chroma appearing more muted or gray. Together, these three attributes help artists create depth, contrast, and harmony in their work.
