I'm not dismissing your concern, but I did amend the doc string prior to 
pushing to state explicitly that it can be used for either foreground or 
background colours.

I didn't bother making separate functions since they would probably have been 
identical anyway, after studying the different cases. Hope that's all right, 
and if you can argue -- after having used it yourself in your own code -- that 
there is an important semantic distinction, then the code can be modified 
accordingly.
