01 When can using colours different from reality be suitable in expression-based art?
Answer and explanation
Correct answer: A. When they clarify the artist's feeling or idea
Explanation: The governing concept is expressive colour, in which colour serves emotional or conceptual communication rather than simple visual copying. An artist may use a blue face to suggest sadness, an unnatural red sky to create alarm, or bright colours to communicate hope and energy. Such choices are suitable when they support the intended feeling or idea, so option A is correct. Option B mistakes expression for pointless confusion. Option C is unnecessary because expressive colour can be used with a clear subject, and D removes the purpose and planning that make colour meaningful.
