GLBLENDCOLOREXT()					     GLBLENDCOLOREXT()

NAME
       glBlendColorEXT - set the blend color

C SPECIFICATION
       void glBlendColorEXT( GLclampf red,
			     GLclampf green,
			     GLclampf blue,
			     GLclampf alpha )

       delim $$

PARAMETERS
       red, green, blue, alpha specify the components of GL_BLEND_COLOR_EXT

DESCRIPTION
       The GL_BLEND_COLOR_EXT may be used to calculate the source and destina-
       tion blending factors. See glBlendFunc for a  complete  description  of
       the  blending  operations.   Initially the GL_BLEND_COLOR_EXT is	set to
       (0,0,0,0).

NOTES
       glBlendColorEXT is part of the EXT_blend_color extension, not  part  of
       the  core  GL  command  set.   If GL_EXT_blend_color is included	in the
       string returned by glGetString, when  called  with  argument  GL_EXTEN-
       SIONS, extension	EXT_blend_color	is supported by	the connection.

ERRORS
       GL_INVALID_OPERATION  is	 generated  if glBlendColorEXT is executed be-
       tween the execution of  glBegin	and  the  corresponding	 execution  of
       glEnd.

ASSOCIATED GETS
       glGet with an argument of GL_BLEND_COLOR_EXT.

SEE ALSO
       glBlendFunc, glGetString.
