Does a palomino's colour stop changing at some age? If so, what age does it typically do that? If there is sooty in there, when would it typically make an appearance?
I'm in the process of buying a 15 month old AQHA filly and I'm just curious what how light or dark she may wind up being, and if the "sooty" appearance on her legs and hips is there to stay or not. I wasn't sure what age (if any) I might be able to safely assume her colour will stop changing (except summer/winter coats, of course). It really doesn't matter either way, I'm just killing time while I wait to go pick her up. :)
This is her at 3 days:
And yesterday, just under 15 months:
ETA: Yes, I know she's overweight, and we'll be taking care of that shortly. Also, she's totally clean in the 15 month photo, no dirt/mud.
