Equal use of many bright colours creates visual clutter in a poster. What is a balanced solution?

Correct answer: Choose one dominant colour and use others as accents

The governing principle is colour hierarchy and visual balance. One dominant colour unifies the poster, while smaller accent colours create emphasis and guide the viewer toward the main message. Adding more bright colours increases competition, equal areas remove visual priority, and adding black to every colour can make the design dull or muddy. Therefore, choosing one dominant colour and using the others sparingly is the balanced solution.
