As an outdoorsman, I like orange G10 on knives to maximize visibility. If you drop your knife in a pile of dirt/leaves/branches, the easier it is to find, the better.
I'm not digging it on the Groove, though. I got the plain versions for Christmas, and love pretty much everything about it - including what I consider to be the classy look of the black G10 with the stainless steel. I don't consider it to be a wilderness type of knife though, so no need for the bright orange.
I still like the idea of of doing an interchangeable Groove - different G10 colors and/or blade shapes/steels, but not in orange.
