Complementary colors and analogous colors works

Quick answer：

Complementary colors and analogous colors are two concepts in color theory. Complementary colors are pairs of colors that, when combined, cancel each other out in the color spectrum, such as red and green. Analogous colors are colors that are next to each other on the color wheel and share a common color trait, like red, orange, and yellow. Artists use these concepts to create harmonious and dynamic compositions in their works.
