Which trio describes the three dimensions often used to describe color, including hue, tone, and saturation?

• A. Hue, Saturation, Brightness
• B. Hue, Tone, Saturation
• C. Red, Green, Blue
• D. Brightness, Value, Chroma

Answer: (B)

Hue, tone, and saturation describe color in three perceptual dimensions: what color you see, how vivid it is, and how light or dark it appears. Hue identifies the color family on the wheel (for example red, blue, or green). Saturation measures how pure or intense the color is; high saturation means a vivid color, while low saturation yields a muted or washed-out appearance. Tone represents the lightness or brightness level, often achieved by adding gray, which shifts the color toward a softer, deeper, or lighter feel.

This combination—hue, tone, and saturation—matches the description in the question, focusing on the three aspects used to characterize color in many contexts. Other options mix in different models (like red, green, blue as additive color channels) or use related terms that don’t align exactly with tone, so they don’t fit the trio described here.
