For stuff I carry, and plan to carry for a LONG time, I prefer stainless steel. It doesn't get all worn/scratched looking. Kind of ageless.For outdoor gear, I like bright colors. Red is good, safety orange or safety yellow are better. That's for SMALL items, so if I drop them, or set it down, I can find it more easily.My current bag is black. It's intended to not draw attention. My backpack is OD green with brown leather bottom, which also just sort of blends in.If you asked for the general 'favorite color' or 'what color game piece do you prefer' kind of color, then Green.However, the simple truth of availability means more items than I would have otherwise chosen are black. Like the old Henry Ford joke: You can have any color you want, as long as it's black.I will simply NOT buy an item if the only available 'color' is camouflage.
Walking around with camouflage gear in an urban environment is an excellent way of being mistaken for a mall ninja. In the forest or the mountains I prefer to be found if having to call for help, and also I prefer hunters to realize there are people around.
I just realised I'd love a safety orange small flashlight. I've temporarily lost my Fenix E01 much too often already, when just putting it down shortly...
