Colours placed near each other on the colour wheel are useful for which effect?

Harmony

The correct answer is D: colours placed near one another on the colour wheel are analogous colours, and they are commonly useful for creating harmony. Because neighbouring hues share some visual qualities, they usually blend or relate smoothly instead of producing the strongest possible opposition. D is correct because harmony means a pleasing sense of agreement among parts of an artwork. A is incorrect because strong contrast is more strongly associated with colours opposite each other, such as complementary colours. B is incorrect because shadow is related to light and dark areas, not simply to neighbouring hues. C is incorrect because texture describes the surface quality or visual feel of a material; colour proximity does not create hard texture. The answer describes a common design effect, not an absolute rule. Brightness, saturation, spacing, and surrounding colours can change the result. Memory cue: analogous colours are neighbours, and friendly neighbours often produce harmony.
