I don't mind the colors from 1.x but I certainly think every other advancement from the later OSes are a plus. The gray can be a bit overwhelming at times but I also don't know too many Amiga users who were satisfied with leaving their desktop colors alone. Most people I knew customized pretty quickly.
With 1.x many didn't because you didn't have many options to do so. Even 2.x gave you tons more to work with.
