Question

Which of the following is NOT a complementary colour scheme?

• A. Yellow-green and red-purple
• B. Blue-purple and yellow-orange
• C. Red and green
• D. Yellow and blue

Hint:

Remember the three classic primary-secondary complementary pairs:
- Red and Green
- Blue and Orange
- Yellow and Purple

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
A complementary color scheme consists of two colors that are directly opposite each other on the standard Prang color wheel.
When placed next to each other, complementary colors create the highest contrast and make each other appear more vibrant.

Step 2: Detailed Explanation:
Let us analyze the relationships of the listed color pairs on the standard 12-color Prang wheel:
- Yellow-green and red-purple: These are tertiary colors located directly opposite each other on the color wheel, forming a complementary pair.
- Blue-purple and yellow-orange: These are also tertiary colors positioned opposite each other, representing a complementary pair.
- Red and green: These are primary and secondary colors, respectively, located directly opposite each other on the color wheel, making them a classic complementary pair.
- Yellow and blue: Yellow and blue are both primary colors.
The complementary opposite of yellow is violet (purple), and the complementary opposite of blue is orange.
Because yellow and blue are not opposite each other on the color wheel, they do not form a complementary color scheme.

Step 3: Final Answer:
The pair "Yellow and blue" is not a complementary color scheme.
