Never mind the names, how about lots of posts coming in lilac. I thought that was something computer clever people did. Only trouble is my halogen lamp washes out the colours.
How long would a newly-registered poster have their name in green? Or, if their names are going to remain green for always, then later newly-registered people would have to be in a different colour to denote they were newer than these current new ones, otherwise we'' have 'old new' muddled up with 'new new'.
