The patch itself looks good, but it would be nice to have a commit
message explaining what's going on and why. Maybe something like:

  Using an enum reduces the number of magic numbers in the code. Note
  that we also use values that allow easier computations. For example,
  colors with type COLOR_ANSI now store the actual foreground code we
  expect (e.g., red=31) instead of an offset into our array, and we can
  switch between foreground/background for all types by adding an
  offset. That will help when we add new color types in a future patch.

Your original dropped the comments here, since we're not saying "3" or
"4" literally anymore. I could go either way, but I think I slightly
preferred dropping them. It might be even nicer if we had
COLOR_FOREGROUND_OFFSET = 0, which you could use instead of the bare
"0".
