I remember seeing one (a Kona, but not a Hot) a few years back that had different colours and different years on each side. Can't remember the colours, but one side I think was the '93/94 square font decals and the other was the earlier '91/92 'K' decals. Nice idea and well executed, if a little 'out there'!
This thread also has some interesting colour schemes for inspiration, including this beauty, a fairly simple scheme that could be easily re-interpreted in other colours?
