I wore brown paddock boots with black half chaps for a year and a half, because at our local tack shop the only Ariat boots they had in my size (5) were brown, and the only chaps they had in my size (short small) were black, and I needed them RIGHT THEN! I didn't care very much, but for clinics and demonstrations I wished I'd had matching ones. For regular riding it was absolutely fine. If it's cold I sometimes ride in Timberlands and my too-big second-hand half-chaps, because they're warmer!
