ImageMagick Color Names
+A number of ImageMagick options and methods take a color as an argument. The color can then be given as a color name (there is a limited but large set of these; see below) or it can be given as a set of numbers (in decimal or hexadecimal), each corresponding to a channel in an RGB or RGBA color model. HSL, HSLA, HSB, HSBA, CMYK, or CMYKA color models may also be specified. These topics are briefly described in the sections below.

The widest ends of both cones are stacked together one on top of the other. Hue is measured around the perimeter. Saturation is measured from the axis outward. Lightness is measured from the bottom apex upward.

Hue is represented as an angle of the color around the circular perimeter of the cone(s) (i.e. the rainbow represented in a circle). Hue values are either integer or floats in the range 0—360 or integer or float percentage values in the range 0—100%. By definition red=0=360 (or 0%=100%), and the other colors are spread around the circle, so green=120 (or 33.3333%), blue=240 (or (66.6667%), etc. As an angle, it implicitly wraps around such that -120=240 and 480=120, for instance. (Students of trigonometry would say that "coterminal angles are equivalent" here; an angle θ can be standardized by computing the equivalent angle, θ mod 360.)
