ColorSpec (Color Specification)
Color specification
Description
ColorSpec
is not a function; it refers to the three ways in which you specify color for MATLAB®graphics:
RGB triplet
Short name
Long name
The short names and long names are character vectors that specify one of eight predefined colors. The RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color; the intensities must be in the range [0 1]. The following table lists the predefined colors and their RGB triplet equivalents.

Examples
To change the background color of a figure to green, specify the color with a short name, a long name, or an RGB triplet. These statements generate equivalent results:
whitebg('g') whitebg('green') whitebg([0 1 0]);
This code changes the figure background color to pink:
fig = gcf; fig.Color = [1 0.4 0.6];
Tips
The eight predefined colors and any colors you specify as RGB triplets are not part of a figure's colormap, nor are they affected by changes to the figure's colormap. They are referred to asfixedcolors, as opposed tocolormapcolors.
In most cases, you can specify a color using either an RGB triplet or a character vector of a color name. However, in some cases, you cannot specify the color as a color name. For example, you cannot set theCData
property of a scatter object to a color name.
