Who said walnut FAs don't make any sense? I'd be wearing them all summer long with my walnut PAs. What else would one wear with tan gabs, dress linens, and seersucker? And the rest of the year: With a tan suit perhaps? Definitely with a tan trouser and blazer combo, or with navy trousers and odd jacket (much better choice than a strand for this combo unless the jacket is obviously on the casual side of things). I'm still bumfuzzled by those who think a tan cap toe shoe is superfluous. Embrace the walnut FA. Nothing wrong with loving a tan punch cap as long as you aren't trying to make them work with a dark suit every day.
