how to tell a no pattern LP?

[dasein]

Ok so I just joined and I've read quite a bit on colors in the forums already, but I'm curious how to tell if a horse has LP but doesn't have spots. When they are older they'll be varnish, right? But what about 4 years old? You see, I am asking because I adopted some tarpans from the AC, and one has a blanket and one is not quite "right" for a normal tarpan color. So I guess my question specifically is, does this wonky grayish colored mane and tail signify LP, and will she varnish out?

Silver is visible from day one on black-based horses.

I don't think she has LP. The diluted colour are caused by the Dun gene, because you can clearly see the markings on her legs, neck and on her back. I thus expect the grayish mane and tail to be caused by the Silver gene, which is visible from day one on black-based horses. As she is a bay (and thus black-based), you would have noticed the silver if you had her as a foal. But since you've adopted her, you can't be really sure though. Know that LP also affects mane and tail - they go white with age.

I would call her a Silver bay dun.

I don't think so. Foundation tarpan don't come in silver. I already know she is bay dun, since that's the only color they come in. I do believe she is LP with no pattern genes (aka "varnish"). My one tarpan with a blanket has the same grayish colored mane and tail, and my other non LP tarpans have normal manes and tails.

This horse is definitely not silver. It is Lp.
