Which of the following is not a complementary colour ?

Question

Accepted Answer

The correct option is 3:
The correct option is 3 because **Blue and Green** are not complementary colors; instead, they are classified as **analogous** colors. Complementary colors are defined as pairs of hues that sit directly opposite each other on the standard color wheel (the RYB model, commonly used in art and design). When these pairs are placed next to each other, they create the strongest possible visual contrast. Conversely, Blue and Green sit right next to each other on the color wheel, often separated only by the tertiary color Blue-Green. This close proximity means they share a common hue (Blue), and thus they harmonize beautifully but lack the intense contrast characteristic of a true complementary pair.

The incorrect option is 1:
The pairing of **Red and Green** is one of the three primary and universally recognized complementary color pairs. Red, a primary color, is situated directly across the color wheel from Green, the secondary color created by mixing the other two primaries (Blue and Yellow). This relationship creates maximum contrast; when seen together, the colors intensify each other, making them an essential tool for artists seeking to achieve high visual tension or drama in their work.

The incorrect option is 2:
The pairing of **Blue and Orange** is another definitive primary complementary color pair. Blue is a primary color, and Orange is the secondary color formed by mixing Red and Yellow. Because they are diametrically opposed on the color wheel, their combination yields the maximum saturation contrast. This powerful visual dynamic, such as the contrast between a cool blue sky and a warm orange sunset, is a perfect example of a complementary relationship.

The incorrect option is 4:
The pairing of **Yellow and Violet** (or Purple) is the final set that completes the three fundamental complementary color pairs. Yellow is a primary color, and Violet is the secondary color resulting from mixing Red and Blue. Their position directly opposite one another on the color wheel ensures they produce the most intense opposition and contrast. This essential relationship confirms that Yellow and Violet is a complementary pair.
