I'd like to see an ACU gray, if the frame is colored densely enough to not show any glass fiber. I don't want it looking like a truck toolbox. I think Walther offered that on a small CCW pistol lately and they seem to be sitting on the shelf because of that - looks too 'Mart. Gray would blend with jeans well, and not look like a gun as much if exposed.
Of course, OD, desert, and pink would be normal variations. I bet we wait quite a while, tho, as color variations are more to spiff up sales for an aging classic - which may take a while.
