A color wheel or color circle [1] is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms color wheel and color circle interchangeably; [ 2 ] [ 3 ] however, one term or the other may be more prevalent in ...
[citation needed] Red, reddish-orange, orange, yellow-orange is one example of a set of analogous colors. A near-analogous color scheme comprises three colors, namely a base color and two colors that are 60 degrees and 300 degrees apart from the base color. The near-analogous color scheme has the same consistency as the analogous color scheme ...
However, the graph obtained from K n by attaching a degree-one vertex to each vertex of K n has a significantly smaller distinguishing number, despite having the same symmetry group: it has a distinguishing coloring with ⌈ ⌉ colors, obtained by using a different ordered pair of colors for each pair of a vertex K n and its attached neighbor.
A mixture produced from two primary colors, however, will be much more highly saturated than one produced from two secondary colors, even though the pairs are the same distance apart on the hue circle, revealing the limitations of the circular model in the prediction of color-mixing results.
These three dimensions can be defined in different ways, but often the most intuitive definition are the dimensions of the HSL/HSV color space: Hue: representing the different colors of the rainbow or color wheel (e.g. 'red', 'orange', 'yellow', etc.); roughly analogous to the color's wavelength or frequency.
In color science, a color gradient (also known as a color ramp or a color progression) specifies a range of position-dependent colors, usually used to fill a region. In assigning colors to a set of values, a gradient is a continuous colormap, a type of color scheme. In computer graphics, the term swatch [1] has come to mean a palette of active ...

A number of color models exist in which colors are fit into conic, cylindrical or spherical shapes, with neutrals running from black to white along a central axis, and hues corresponding to angles around the perimeter. Arrangements of this type date back to the 18th century, and continue to be developed in the most modern and scientific models.
