A color scheme refers to a combination or arrangement of colors that are used together in an artwork, design, or decor. It can also refer to the specific colors chosen for a particular purpose, such as matching clothes or painting a room. The term is often used in interior design and graphic arts to describe the overall palette of colors used in a project. A color scheme can be monochromatic (using different shades and tints of one color), analogous (using colors that are next to each other on the color wheel), complementary (using colors opposite each other on the color wheel), or triadic (using colors equidistant from each other on the color wheel).
