ColorSpec

Purpose

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.

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:
