  The second format of this command allows the user to turn on or off any of the valid modifiers.

  The third format of this command allows the user to change the intensity of specified colors on platforms that support changing the content of a color (X11, Windows GUI). The specified color can be changed by supplying the intensity of red, green and blue. These are numeric values between 0 and 1000 inclusive. eg To change red to blue : SET COLOR RED 0 0 1000. All characters being displayed as red will be displayed with the specified intensities. Note that this behaviour is not consistent across platforms, and should be considered experimental at this stage.

  It is an error to attempt to set a colour on a mono display.
