Which answer writes colour effect most correctly?

Warm red and orange colours give energy and excitement.

Direct answer: D. Red and orange are commonly treated as warm colours, and they can suggest energy, warmth, activity, and excitement. Colour effect is studied by connecting a colour with the feeling or visual attention it may create in a particular context. The word “may” or “can” is important because colour meanings are not identical in every artwork or culture; combinations, subject matter, brightness, and context also matter. Option A is too absolute because blue does not only make a picture bright; brightness depends on value and surrounding colours. Option B is wrong because green does not create sadness in every painting. Option C is wrong because black does not always symbolise happiness and celebration. Option D gives a commonly accepted warm-colour effect without claiming that it is universal. Memory cue: warm colours often suggest heat and energy, while cool colours often suggest calmness, but always check the context.
