In terms of looks, afaik 2000 is a bit lighter and possibly shaded red a little—not so grey. Not much else differs externally, though.

Ah, and I also remembered that 2000 loved header panels at top of windows, with white background and a little artwork in them. This also worked to make the interface considerably brighter than in 98.

(Though ME did have some white-background panels with large headers and graphical fluff, where I think previously you'd only find grey. In this vein: https://www.operating-system.org/betriebssystem/bsgfx/micros...)
