A colour name such as red or blue tells which quality?

Hue

The correct answer is A: hue is the quality that identifies a colour by its basic name, such as red, blue, yellow, or green. To solve the question, ask, “Which colour is it?” The answer to that question is the hue. Hue is different from value, which tells whether the colour is light or dark, and from saturation, which describes how strong or muted the colour appears. Option B is wrong because texture describes a surface quality, such as smooth, rough, soft, or grainy. Option C is wrong because a line is a mark with length and direction. Option D is wrong because form refers to a three-dimensional object or the appearance of volume. None of these terms names the colour itself. Memory cue: hue is the colour’s identity, value is its lightness or darkness, and saturation is its strength or purity.
