What are colors that are opposite each other on the color spectrum referred to as?

Colors that are opposite each other on the color spectrum are referred to as complementary colors. This pairing is significant in the field of color theory, where complementary colors enhance each other's visual impact when placed next to one another or combined in various mediums.

For instance, in traditional color theory, the complementary color of red is green, while blue pairs with orange, and yellow contrasts with purple. This relationship is often used in art, design, and photography to create visually striking compositions and to achieve a desired mood or effect. The contrast between complementary colors can be harnessed to create depth and vibrancy in artwork, making them a fundamental concept in understanding color interactions.

In contrast, analogous colors are those that are next to each other on the color wheel and typically share a common hue, creating a harmonious look. Primary colors are basic colors that cannot be created by mixing other colors and are the foundation for creating a wide spectrum of other colors. Secondary colors are produced by mixing two primary colors together, further contributing to the broader understanding of color relationships, but do not represent the concept of opposition that defines complementary colors.
