I think we're talking about the same thing. I was referring to the split 
regular expression, and the question is, "for the current element of 
split(/\s+/, $str), does it match a color?"

Anyway, I preferred the regex version for readability, though I should 
have used the /x modifier--it would still take two lines, but it would 
not need to attempt two matches. As for misconfigured color 
configurations, should we catch that? I wrote this with the intent that 
it should ignore invalid color names, but it would probably be more 
useful to print a warning.
