Apparently rum comes in colours. Perhaps most things do. The colour of magic, according to Terry Pratchett at least, is called Octarine. Which, incidentally, is a great name for a band. Naturally, there was actually a UK group called exactly that - they had a couple of trance hits in the '90s, the very decade in which this tasty rum was distilled. Bringing this bit of text back around to relevance. Sort of.
