2ColorSpec
Purpose Color specification
ColorSpec
Description ColorSpec is not a command; it refers to the three ways in which you specify
color in MATLAB:
• RGB triple
• Short name
• Long name
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.
RGB Value Short Name Long Name
[1 1 0] y yellow
[1 0 1] m magenta
[0 1 1] c cyan
[1 0 0] r red
[0 1 0] g green
[0 0 1] b blue
[1 1 1] w white
[0 0 0] k black
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')
