What defines complimentary colors in the context of color theory?

Complementary colors are defined as colors that are directly opposite each other on the color wheel. In color theory, this relationship is significant because complementary colors create contrast and enhance each other when used together. For instance, when placed side by side, they can make each other appear more vibrant. Additionally, when mixed, complementary colors tend to neutralize each other, often resulting in a muted or grayish tone.

Understanding this concept is crucial for estheticians, particularly in makeup application and design, where contrasting colors can be employed to achieve certain effects or to draw attention to specific features. This knowledge can also assist in color correction techniques, where the use of complementary colors can help counteract unwanted tones in cosmetics or skin treatments.
