Kenilworth: Walnut or Burnished Brown?

[HJ15]

Hello all. I have been looking for a brown, plain toe show for quite a while. When I saw the AE Kenilworth, I knew that was the one I wanted. But now I can't decide whether to get it in walnut or burnished brown. I want it to wear with Navy, light gray, khaki, etc. I already have a nice pair of black Bruno Magli cap toe leather shoes and need to add a brown pair. I'll likely get both colors eventually - just looking for advice on which to get first in the Kenilworth.

I'm young and the environment I work in suggests (but doesn't require) me to wear a suit. So I'm not too worried about what is "right" or most conservative. If you're familiar with this shoe in both colors, I would really appreciate hearing your thoughts.

Thanks!
