What is generally created when grey is added to a colour?

Correct answer: Tone

The governing concept is the three-part distinction among tint, tone, and shade. Adding grey to a pure colour produces a tone, which reduces the colour’s intensity or saturation and often makes it appear softer or less vivid. Thus option B is correct. Adding white creates a tint by increasing lightness, while adding black creates a shade by lowering lightness. A complementary colour is a relationship between hues, not the direct result of adding grey.
