I don't think is ugly at all. It is a very utilitarian piece that's true. I mean the M4 (or 4-gery) with all those tacticool accessories is as ugly as a gun can get...same is true for an M14 style rifle with all the wacky stuff on it...now that's ugly! At least the SCAR starts out with all the rails and stuff it needs built in.
As for the color. I kind of like the desert tan, coyote, dark earth thing in general but I don't think FN has executed it very well on the SCAR...too yellow.
I think a muted gray, not too blue, maybe a little green would be a better color or an improved coyote color...darker, browner, and greener.
