Well, I don't think it is complicated
It's one of my "magic" colors so guess I am biased.
Agreeing with the options offered above - especially olive with following combinations:
white and black (say a white blouse with a cropped chunky black sweater or tailored black jacket...mmm velvet!!)
juicy berry tones, cordovan.
white and navy (or royal blue)
blush and black (or navy)
lumberjack plaids
substitute cream/ivory for white in the above
always works with any shade of denim.
I don't see it with yellows or oranges or rusts - not my personal preference. Seems too forced "autumn" maybe. Again, a personal preference. Maybe brown, but I'd prefer the brown item to have a really distinctive texture so you get some dimension in the tones and not a blah expanse of it.
