I like any colors really.
I agree with TT, I love Blue lol.
But, camo for EDC is not a huge deal.
I live in the city(where I'm around a huge amount of several kinds of people all the time) and I carried a Spyderco Para2 in Camo, and a Spyderco Manix 2 in all Black for a long time.
As long as you just take it out, use it for what you need to, and then put it back in your pocket, you should be good to go.
I now carry a ZT 0560 and Spyderco Stretch daily. The sizes and shapes of these two kinda look like weapons, but I've had no problems.
