James, if you want to get rid of that ugly colourArrayToTrim business on your version, just replace the regex with:
hex = Regexp.new(/#([0-9a-fA-F]{3,6})/)
(note the single parenthesis that captures the entire hex number).
also after scanning, something like
colourArray.sort!.uniq!
might be useful, though i haven't checked your new modification and don't know how it will play with line numbers...
Good effort none the less (liked it so much, I even read up on ruby documentation for the first time ever to figure out how to change a thing or two.. ;)

However I had some spare time this afternoon and added line numbers and made the links work on mine.
