GLBLENDCOLOR(3G) [FIXME: manual] GLBLENDCOLOR(3G)

glBlendColor - set the blend color

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

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

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).

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.
