wn_read_user_defined_color

	status.i4.v = wn_read_user_defined_color(red_intensity.u2.r,
						 green_intensity.u2.r,
					 	 blue_intensity.u2.r)

	This routine retrieves the current user defined color values
	as set by a previous call to wn_user_defined_color_c.

	red_intensity	returned red color intensity
	green_intensity	returned green color intensity
