Adult Appaloosa changing colors

[Aematt03]

Hello!

So I, nor anyone in my family, have never owned (what I think is) an Appaloosa. I had someone tell me he is a knabstrupper but I'm not quiet for sure about that. He is somewhere in his 20's and for the past couple of year has been a black and white leopard appy. He almost looked grey and flea bitten due to all of the little spots he had. All of his spots are now turning brown. I can see the bigger ones on his butt in mid color change and he is getting bigger brown ones towards the front. Is this common? Just curious

Got any pictures? @chev is excellent on colours, if she could see him it would help

Appaloosa is a breed not a colour, you can get many breeds that show the spotted coat that is often associated with appys but they must show other specific characteristics as well to be an appy, or of known parentage or be DNA tested
