How do artists and designers use color harmonies, such as monochromatic, analogous, and triadic schemes, in their work?

Color harmonies are combinations of colors that are aesthetically pleasing when used together. Artists and designers use these schemes to create visual interest and balance in their compositions. Monochromatic schemes use variations of a single color, analogous schemes use colors that are adjacent on the color wheel, and triadic schemes use three evenly spaced colors on the wheel.
