How does combined use of colour temperature and value increase depth?

Correct answer: Cool light colours may recede and warm dark colours may advance

Direct answer: A. Colour temperature describes warm colours, such as reds and oranges, and cool colours, such as blues and blue-greens. Value describes lightness and darkness. In many visual compositions, cool and lighter areas can appear to recede, while warmer and darker areas can appear closer or advance. This is not an absolute rule; atmosphere, size, overlap, sharpness and context also affect depth. However, using both temperature and value gives the eye two related spatial cues. A is correct because it describes a plausible and commonly taught arrangement of these cues. B is wrong because colour and value differences can influence spatial reading. C is wrong because value contrast and value changes are important tools for separating planes and forms. D confuses colour temperature, a visual colour relationship, with tactile sensation. Memory cue: cool-light often recedes, warm-dark often advances, but treat it as a helpful tendency rather than a guaranteed law.
