Which of the following color types typically uses vibrant or darker values?

Chroma refers to the purity or intensity of a color, which can indeed include vibrant or darker values. High chroma colors are those that are more saturated and vivid, meaning they stand out more prominently compared to muted or less saturated hues. When discussing color theory, the idea of chroma encompasses how vibrant or intense the colors appear to the eye.

In contrast, tints are created by adding white to a color, resulting in lighter variations. Pastels also involve light hues and generally do not reflect the vibrancy associated with high chroma. Shades, on the other hand, involve adding black to a color, which darkens it but does not necessarily highlight the color's inherent vibrancy. Thus, chroma is the most appropriate term when specifically discussing the essence of vibrant or dark color values, emphasizing richness and intensity.
