Which term refers to the intensity, strength, or purity of a color?

• A. Achromatic
• B. Black
• C. Chroma
• D. Tint

Answer: (B)

The focus here is on how vivid or pure a hue appears. That quality—how strong or saturated a color is—is called chroma. High chroma means a color is bright and pure, while low chroma means it’s dull or washed out. Achromatic describes colors without any hue (grayscale). A tint is a lighter version of a hue created by adding white, which lowers both value and chroma. Black refers to the darkest value, not the purity of the color. So, the term that best matches intensity or purity is chroma.
