As luck would have it, my colleague Kenny just ordered a pair of these so I'm attaching an image which might help. It's a very sharp looking shoe and actually very diverse. You could easily wear this with black, charcoal, grey or even khaki slacks. I understand where you might see some brown hues, however. This print could take on some brown tones if worn with brown pants, but charcoal is definitely the dominant color and the accents are black when seen up close.
Hopefully this helps.
