Color specification
Description
ColorSpec is not a command; it refers to the three ways in which you specify color in MATLAB:
The short names and long names are MATLAB strings that specify one of eight predefined colors. The RGB triple 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 equivalents.

Remarks
The eight predefined colors and any colors you specify as RGB values are not part of a Figure's colormap, nor are they affected by changes to the Figure's colormap. They are referred to as fixed colors, as opposed to colormap colors.
Examples
To change the background color of a Figure to green, specify the color with a short name, a long name, or an RGB triple. These statements generate equivalent results:
whitebg('g')
whitebg('green')
whitebg([0 1 0]);
You can use ColorSpec anywhere you need to define a color. For example, this statement changes the Figure background color to pink:
set(gcf,'Color',[1 .4 .6])
