Which best defines "complementary colors"?

Complementary colors are defined as colors that are opposite each other on the color wheel. This means that they have a unique relationship in terms of visual contrast. When placed next to each other, complementary colors enhance each other's intensity, creating a vibrant and dynamic effect. For example, blue and orange are complementary colors; when used together, they can create a striking visual impact. This concept is fundamental in color theory, particularly in art and design, as it helps artists achieve visual balance and harmony in their work.

Although there are other relationships between colors, such as those that blend harmoniously or those that are adjacent on the color wheel, these do not capture the specific definition of complementary colors. Similarly, while colors can express different emotions, this characteristic is not inherent to the definition of complementary colors themselves.
