Colours found opposite each other on the colour wheel are called?

Colours that are located opposite each other on the colour wheel are referred to as complementary colours. This relationship means that these colours create a strong contrast when paired together, enhancing each other's visual impact. For instance, the complementary pairing of red and green or blue and orange is commonly used in design, art, and hairstyling to create striking combinations that draw attention.

Understanding complementary colours is essential in hairstyling, as they can be used effectively to correct tones and enhance features. For example, in colour correction, sometimes a stylist may use a colour opposite the target tone to neutralize undesirable hues. This concept is crucial in formulating hair dyes and choosing hair colours that will harmonize or contrast effectively with a client's skin tone and eye colour.

In contrast, primary colours are the building blocks of all other colours but do not involve oppositional relationships, while secondary colours result from mixing primary colours and likewise do not exhibit the same direct contrast. Analogous colours, which are hues that sit next to each other on the colour wheel, promote harmony rather than stark contrast.
