In which scene would the dominance of warm colours be most appropriate?

Correct answer: Glowing sun

The governing concept is colour temperature and visual mood. Warm colours such as red, orange, and yellow suggest heat, light, energy, and activity. A glowing sun therefore suits a dominant warm palette, making option A correct. A calm lake, icy night, and misty snowfall are more naturally represented with cool blues, blue-greens, or violets. The answer depends on the atmosphere of the scene, not merely on the number of colours used.
