Color scheme
In color theory, a color scheme is a combination of 2 or more colors used in aesthetic or practical design. Aesthetic color schemes are used to create style and appeal. Colors that create a harmonious feeling when viewed together are often used together in aesthetic color schemes. Practical color schemes are used to inhibit or facilitate color tasks, such as camouflage color schemes or high visibility color schemes. Qualitative and quantitative color schemes are used to encode unordered categorical data and ordered data, respectively. Color schemes are often described in terms of logical combinations of colors on a color wheel or within a color space.[1][2][3]

Practical color schemes combine colors outside typical aesthetic media and context for purely practical reasons, generally focusing on maximizing or minimizing contrast, instead of color harmony. The most common practical color scheme is black-and-white, which generally maximizes contrast. This may be used for black text on a white background or prison uniforms. Enhancing contrast against a background motivates some practical color schemes, such as high visibility color schemes, while inhibiting contrast against a background motivates others, as in camouflage.
