A color scheme typically refers to a set of colors used together in design. In this context, a 'color scheme with 6 colors' implies a selection of six hues that are coordinated to create a harmonious and visually appealing composition. This could be used in various design fields such as graphic design, interior design, fashion, and art. Designers often consider color theory principles like complementary colors, analogous colors, and monochromatic palettes when creating a 6-color scheme.
