01 Which colour is useful for showing energy in a festival poster?
Answer and explanation
Correct answer: A. Red
Explanation: The governing concept is the emotional and visual effect of colour. Red is a warm, high-energy colour associated with fire, excitement, celebration and urgency, so it attracts attention quickly in a festival poster. Grey, light blue and muted green usually create quieter, cooler or more subdued impressions. Red should still be balanced with other colours so that the design remains readable and does not feel overwhelming.
