I agree, the original WB colours were far better than the greys of WB2.0 +.
The colour scheme of the original WB is being used by Apple and Microsoft, so It seems that it is very modern.
Personally I would like OS4 to use these colours again to bring the original Amiga look bang up to date. In a sense this would tell past users that a real Amiga is back while underlining the great heritage the OS has with what are considered modern functions.
