Is there a list giving RGB values for different predefined colors?

There should be a list relating different colors (such as green, red, etc.) to their RGB values which I can reference directly from my code.

The COLORSPEC documentation gives a list of predefined colors and their RGB equivalents. This can be found at:

For a visual on more color options which do not have predefined names in MATLAB, open the Colormap Editor by typing

colormapeditor

at the MATLAB prompt. Hovering your mouse pointer over the displayed colorbar will display corresponding RGB values.

To access the RGB values from the command line, you can look at the RGB values of the currently selected colormap by typing

colormap

at the MATLAB prompt. This will return an m-by-3 matrix of real numbers between 0.0 and 1.0. Each row is an RGB vector that defines one color. For more information on the different colormaps available, visit the colormap documentation at:
