Step 1: Understanding the Concept: Accented Neutral Colour Harmony involves the use of a dominant neutral color combined with a bright pop (accent) of a primary or secondary color.
Step 2: Detailed Explanation: Neutral colors include black, white, gray, beige, and brown.
An accent is a small amount of a bright color used to add visual interest.
In option (A), the 'white frock' provides the neutral base, while the 'red belt' serves as the bright accent color.
Options (B), (C), and (D) use base colors (pink, yellow, red) that are not considered true neutrals in classic color theory.
Step 3: Final Answer: A white frock with a red belt is the perfect example of accented neutral harmony.
