Wow, this is really an open ended question!
Sneaky, on the paint, I use Krylon Fusion designed to bond with cordura material! Works great on all sorts of tac gear!
Heres my attempt at a sort of ATACS look. It looks better now that the bag has been beat a little, and I still need to add another light brown to it. I was goin for woodland camo colored ATACS on a black base.
So I guess it really depends on what the gear is for youre wanting to color co-ordinate.

Me, for the woods and fields around here, I like multicam, foliage and the Dry Earth. And just as Shooter mentioned, if youre hunting, always defer to local laws. AND! as Sneaky pointed out and clarified for us, ghillie suits arent always appropriate. The moral of the story there I think, is that, just because its camo, that doesnt mean its working. The wrong camo for the enviroment, is like not being camo'd at all.
I think thats what Sneaky was sayin... yeah, clearly that was the intended point of that pic!
