01 How can changing the colour of a line change the expression of a picture?
Answer and explanation
Correct answer: A. The mood, emphasis, and visual effect of the line can change
Explanation: Colour adds emotional and visual meaning to a line, so changing the line from black to another colour can alter the expression of the whole picture. A warm red or orange line may feel energetic, urgent, or lively, while a cool blue or green line may suggest calmness, distance, or quietness; the exact effect also depends on surrounding colours and contrast. A bright line can attract attention, whereas a low-contrast line may recede. Option A is correct because colour changes mood, emphasis, and visual impact. Options B, C, and D describe effects that do not automatically follow from changing a line’s colour.
