Thanks Egg, I'll play around with that although a quick test of converting to web colours and then to 16 colour index still seems to result in me losing some when bringing into the editor. And what's happening is that it is reducing the colours and dividing them up seemingly at random - so while the red bits may go a blue that is already used, that blue is now also corresponding to bits that were blue to begin with. Meaning if I change that blue, it changes in other places. I'm a little confused but I may well figure it out.
