Using flexible syntax to denote color composition in terms of basic colors, colormix creates an RGB vector with the colors mixed according to one of three mixing modes.
Basic colors are: red, green, blue, cyan, magenta, yellow, black, white.
Used standard MATLAB color string shorthands.
E.g. RGB = colormix('cwCg') combines two parts cyan, one part white and one part green to create a new RGB color.
Order and case do not matter.
May also use numbers: colormix('10kr') has 10 parts black to one part red.
Mixing modes are linear combination and the additive- and subtractive light models.
