Yes I have orange.
Off memory on hand I have the following in 500d unless otherwise noted: coyote (also 1000d), foliage green, ranger green, orange (also 1000d), black (I think I have some 1000d too), multicam, highlander, and a bit of typhoon. I can order other colors for a project by the yard if needed, not really cost effective for a small project unless you really want that color but for a pack or such its not a big cost driver in the grand scheme. I'm sticking with coyote and black trim work for the foreseeable future as its a lot to stock up buckles/webbing/zippers/etc. in other colors.
Not sure what you're looking for in terms of access/retention.
