Which sentence explains the use of tone most correctly?

Correct answer: Adding grey can reduce a colour’s intensity, making it appear muted and controlled.

Correct answer: C. In colour theory, a tone is generally made by mixing grey with a colour. Grey reduces the colour’s intensity or saturation, so the result looks less bright, more muted, and often more controlled. Step by step, distinguish the three terms: adding white creates a tint, adding black creates a shade, and adding grey creates a tone. A describes a tint, not a tone. B describes a shade, not a tone. D is too narrow because value and tone may help suggest volume, but tone is not used only for that purpose. A useful memory cue is: tint–white, shade–black, tone–grey. Do not confuse the everyday meaning of “tone” with this specific colour-theory meaning.
