How can colour temperature help in showing depth?

Correct answer: Warm colours may appear forward and cool colours backward

Answer: A, warm colours may appear to come forward and cool colours may appear to recede. Colour temperature is a visual classification: reds, oranges, and yellows are commonly called warm, while blues and some blue-greens are commonly called cool. In a picture, artists can use this difference together with value, size, overlap, and detail to suggest space. A warm area may attract attention and seem nearer, while a cool area may feel quieter or farther away. The word “may” is important because colour temperature is not a fixed rule; lighting, surrounding colours, value, and the subject can change the effect. B is wrong because colour relationships can contribute to different spatial impressions. C is wrong because colour temperature is a visual idea, not a physical heat that must be felt by touch. D is wrong because artists can use warm-cool relationships as one device for suggesting depth. Memory cue: warm colours often advance, cool colours often recede, but check the whole composition.
