Is that what you're running in your CE instance? You're right, I forgot about 
that; and that does make it output color on the terminal. But not CE.

I _think_ what's happening is that CE isn't acting like a tty, so clang won't 
output it in color even if I specify `--extra-arg="-fdiagnostics-color"` (which 
the analogous `--extra-arg="-fno-diagnostics-color"` _will_ turn off color on 
the command-line.)
