The palette thing is one of many things that go under what cRPG seem to lack, and that is a grand vision for WHAT IT WANTS TO BE.
I'd say the devs have good judgement on many matters, just that the work lacks dreams and direction. Of course, this patchwork anarchy has it's advantages. cRPG develops dynamically hand in hand with the players. This creates a loyal playerbase and it's own free spirit. It is not trying to force a theme down our throats so to speak, and we are free to make our own stories..
It is also hard to keep a theme going without restricting armours and weapons (like in the WoW tier system), as players will always try to look as unique as possible. The unique look of each player is one of the strongest most special things about cRPG that one can't find in many other games.
Never the less, I think some dreams and goals about what cRPG should be could really motivate both dev team and players alike to feel they are moving towards something great. It should be room for inventing a kind of theme without destroying what is unique already.
If one could agree on that, a palette choice, what kind of weapons we want to expand upon, armours, locations, even game modes would rise naturally from that choice.
