Hi Dave, Yes, it's legal. Drivers should handle NULL color buffer bindings and there is a test for it: http://cgit.freedesktop.org/piglit/commit/?id=ff2398a4e3c4805e7d1bea38f4ae6f9811b42ede
I fixed it just recently. That said, I think we don't have to bind NULL color buffers which appear at the end of the color buffer list.
