One color as transparency.

Hi, I use OpenGL and GLUT and I was wondering whether there's a way to tell OpenGL that a certain color will represent alpha without using RGBA as the internal format.
Thanks in advance.

yes in theory, just create a shader that discards fragments/pixels of a certain color.
But shaders are expensive, so it's better to use the alpha channel.
