I have been told by my other friends with appy's about some of the color changes their horses have gone through....sort of like watching your baby grow up and evolve into something brand new! I am very curious to see his changes over the years!
That is a good question! He is gorgeous by the way. I would think he probably would go a bit lighter, but because of the appy genes I would guess he wont grey out completly.
Don't take my word for it tho as I'm really not sure.
Just one of the many appy patterns, and it does progress with age. Other appy patterns don't, although the pattern MAY come through slightly differently after each shedding. You can tell varnish apart from classic roan because classic roan never affects the face. It's quite easy to tell apart from grey too - it just doesn't look the same.
If your horse lives long enough and this is varnish roan (I'm not convinced it is - could be one of the other patterns doing a fairly god impression of it), he should turn completely white. Often varnish roan horses will have little patched of dark skin left on their 'bony' parts though - ie the hip, cheekbone etc.
