If calm harmony is needed in a sea scene, which colour scheme is better?

Correct answer: A blue-green analogous scheme

Direct answer: B, a blue-green analogous scheme. Analogous colours are located near one another on the colour wheel. Blue and green are neighbouring colours and are commonly associated with a cool, connected impression that can suit water, sky, and natural surroundings. Because the colours are related rather than strongly opposed, transitions can feel calm and harmonious. A is less suitable because red and green are complementary and create a strong contrast. C is less suitable because black and white produce very high light-dark contrast, which can be dramatic rather than quiet. D is less suitable because an orange-only warm scheme does not naturally support the cool, restful feeling usually sought in a sea scene. This does not mean every sea painting must use only blue and green; it means that, among these choices, the analogous relationship best supports the stated mood. Memory cue: neighbouring colours usually help harmony, while opposites create stronger contrast.
