RGBcolor(3G)							  RGBcolor(3G)

NAME    [Toc]    [Back]

     RGBcolor -	sets the current color in RGB mode

C SPECIFICATION    [Toc]    [Back]

     void RGBcolor(red,	green, blue)
     short red,	green, blue;

PARAMETERS    [Toc]    [Back]

     red     expects the value indicating the intensity	of the red component.

     green   expects the value indicating the intensity	of the green

     blue    expects the value indicating the intensity	of the blue component.

DESCRIPTION    [Toc]    [Back]

     RGBcolor sets the red, green, and blue color components of	the currently
     active GL framebuffer, one	of normal, popup, overlay, or underlay as
     specified by drawmode, to the specified values.  Alpha, when supported,
     is	set to the maximum value.  The current framebuffer must	be in RGB mode
     for the RGBcolor command to be applicable.	 Most drawing commands copy
     the current RGBA color components into the	color bitplanes	of the current
     framebuffer.  Color components are	retained in each draw mode, so when a
     draw mode is re-entered, red, green, blue,	and alpha are reset to the
     last values specified in that draw	mode.

     Color component values range from 0, specifying no	intensity, through
     255, specifying maximum intensity.	 Values	that exceed 255	are clamped to
     it.  Values less than 0 are not clamped, and therefore result in
     unpredictable operation.

     It	is an error to call RGBcolor while the current framebuffer is in color
     map mode.

     The color components of all framebuffers in RGB mode are set to zero when
     gconfig is	called.

NOTE    [Toc]    [Back]

     RGBcolor can also be used to modify the current material while lighting
     is	active (see lmcolor).
