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.
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:
You can use ColorSpec
anywhere you need to define a color. For example, this statement changes the figure background color to pink:
