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).
glBlendColor is part of the ARB_imaging subset. glBlendColor is present only if ARB_imaging is returned when glGetString is called with GL_EXTENSIONS as its argument.
