We used to have black tack previously and so long as it all matches and you have the correct bit, etc. no problem. my daughter prefers brown, so we now have that as well!!! don't forget that no ornamants allowed, ie no crystal headband unfortunately, shame as they look so pretty in the tack shops! also no rubber reins either. i would suggest that you get slightly longer reins too for HUS so you can get a good drape in the rein. hope this helps.

looking forward to seeing you out there.
