My nicer gear is tan/ FDE. Most of my OD stuff is leftover from my airsoft days, and generally lower tier gear (Condor/ UTG).
For a good chunk of the spring and fall, most of the foliage is a light brown color. OD works alright, but it is best in the summer. In the winter, you will either blend in with the snow, or you'll blend in with evetything that isn't snow. In an urban setting, you won't blend in with much of anything, unless you are trying to blend in with a crowd, and that takes more of a "gray man" approach than matching colors.
