Darker pair of brown shoes to go with gray pants

My only brown pair of dress shoes are wingtips in a light tan. I need a second pair of brown dress shoes and want them dark enough to go with gray pants. I don't really like a red burgundy so was aiming for a medium to medium~dark brown. What are your thoughts on bourbon shoes and gray pants? The bourbon seems a different shade than medium to dark brown. (AE has a nice bourbon cap toe in shoebank).
