Changing Muzzle Color

My palomino mare's muzzle changed from black in the summer like this:



To matching the rest of her coat during the winter and even showing a little snip I couldn't see in the summer, like this:



I'm sure this is normal and part of the summer to winter coat change, but is there a name for this?

Havana's muzzle goes from black in Summer to reddish brown in Winter. Confuses me sometimes...wish it would stay black.

He's just getting a hairy-er nose. Most horses go through the same thing every season change, it's just not as noticeable. =]

I don't think there is a specific name for it, it is just a part of them growing the winter hair. Dobe does the same thing, black in the summer and white in the winter.

Ya know, I think her overall color is prettier in the summer (darker palomino), but I don't like the dark muzzle. The muzzle lightens in the winter, but so does the rest of her. I guess I just can't win, huh? LOL

I just thought there might be a name for a dark muzzle on a light horse since it seems common and there seems to be a name for every other possible mark on a horse's face - star, stripe, blaze, snip, etc. Oh well. Maybe I'll just come up with a name for it myself - I'll have to think about that for a while.

Well make sure you let us know when you come up with that new word!
