The complementary colors of hue

Quick answer：

The concept of complementary colors in the context of hue refers to a pair of colors that are opposite each other on the color wheel. In the context of color theory, complementary colors are those that, when combined, produce a grayscale color. For example, red and green, or blue and orange are complementary pairs. When mixed together, they tend to cancel each other out, resulting in a neutral or gray color. This principle is fundamental in design and art for creating balance and contrast.
