The thing about paints is because you can't always tell them apart, which is why halters, leads, reins, saddlepads, grooming tools and boots (unless leasers bought personal stuff) are the same color of the horse. For example, my horse has lime green supplies. Another horse named Monty has maroon supplies. Rose has pink supplies. Just to say so lol.
I prefer nylon halters. They come in different colors so you can match Tack. But it also comes in handy with a place like where I ride when all the horses are paints lol. They also don't rub your horse's face, if fitted correctly. They also come off easy in case of emergency. They are also soft, which I like, and they are easy to punch extra holes into in case the halter doesn't fit but you don't want to buy a new one.
Rope! Check out the Clinton Anderson halters. They have two knots on the pressure points of the nose for control. The rope will NEVER break no matter how much your horse pulls on it. And the feel your horse has is much greater than any nylon or leather halter. In nylon and leather they have more leverage to push back against you! Hope this helps! If you buy a rope halter, don't cheap out! Go for parelli or Clinton Anderson. They last forever! :)
nylon and leather I don't like rope halters because they can fall off easier and aren't as strong and can break easier also they don't always adjust to your horses head(no one at my barn has ever used rope halter)
