NAME

       glBlendColor - set the blend color

C SPECIFICATION

       void glBlendColor(GLfloat red, GLfloat green, GLfloat blue, GLfloat alpha);

PARAMETERS

       red, green, blue, alpha
           specify the components of GL_BLEND_COLOR

DESCRIPTION

       The GL_BLEND_COLOR may be used to calculate the source and destination blending factors.
       The color components are clamped to the range 0 1 before being stored. See glBlendFunc()
       for a complete description of the blending operations. Initially the GL_BLEND_COLOR is set
       to (0, 0, 0, 0).

NOTES

       The type of the red, green, blue, and alpha parameters was changed from GLclampf to
       GLfloat. This change is transparent to user code and is described in detail on the
       removedTypes() page.

ASSOCIATED GETS

       glGet() with an argument of GL_BLEND_COLOR
