What color AE Park Avenues to go with a navy and medium gray suit?

Assuming black is out of the question it would be between merlot, dark brown, chili, and walnut.

My gut tells me to go with either dark brown or merlot but I'm not sure which is more suiting between those two colors.

What's wrong with black? Aside from walnut with navy (which I'd probably do anyways depending on the situation) I would have no problem with any of those colours with either suit.

Black shouldn't be out of the question, but I'd go with dark brown before I went with burgundy.
