Customize a Color Scheme

Color schemes translate color names requested by client applications into red, green, and blue (RGB) values. If you are using a client that explicitly references a color name (for example, "rosybrown") that is not in the default color scheme, you will need to customize the session's color scheme to include the name.

For some client applications, you can determine which colors are required by examining the command line that starts the application. For example, the following command starts an xterm with a gray2 foreground and a cyan2 background:

/usr/bin/X11/xterm -fn 6x13 -sb -ls -d %IP#% -fg gray2 -bg cyan2 &

For other clients, an error message that references the missing color is displayed when the client fails to start. In the following example, the leaf application cannot start because the color rosybrown is missing. 

Can't allocate named color rosybrown 
leaf: Can't create window
