I think, there is nothing wrong with foliage green, I just do not like it. Also I agree with Sverre, on some knives like Manix it looks OK, but I absolutely hate it on Rookie and Schempps. I love orange, I love my orange UKPK, my ladybug, it would be great on Dodo, but I do not like it on Milly. IMHO black is most universal color for knife handles, probably any knife will look good with black handle, also it is very practical. All other colors can be nice on some knives and not so nice on others, just my opinion.
