-- | Usage: @'glBlendColorEXT' red green blue alpha@
--
-- The parameter @red@ is a @ColorF@.
--
-- The parameter @green@ is a @ColorF@.
--
-- The parameter @blue@ is a @ColorF@.
--
-- The parameter @alpha@ is a @ColorF@.
--
-- This command is an alias for 'Graphics.GL.Internal.Shared.glBlendColor'.
