I do have a nice custom made holster with Ostrich trim that happens to match my Lucchese boots that have Ostrich trim and the same basic leather colors, but that is a happy accident, and neither match my belt. My primary belt (and since I've lost so much weight, currently my only belt) is a shade of tan. I own two other holsters that are similar in color to the belt, but again, that is a happy accident. I have nothing, belt or boots, that matches the cordovan color of a couple of my holsters.
So no, I don't worry about it. I buy good equipment, but it doesn't always match, and I don't care. I'm of an age where I'm allowed to have mismatched socks or forget to zip my fly, and people are just supposed to smile and think t's cute. Anyone who mentions it is just being nasty to the elderly.

Also, and even though OC is not my primary carry habit, I figure that either (A) the person who sees my gun will be so agog or freaked out that they won't notice the sartorial faux pas, or (B) the person who sees my gun will be amused to see that grampy is packin'........ and hold the door open for me.
