I think he's strawberry roan/red roan, but I'm not sure nor am I an expert at colour genetics and his papers say he's a chestnut overo. His sire is a black tovero and his dam is a sorrel. I just want to hear some thoughts one what others thing he is. So here are a few pictures throughout the year.
Mid Spring probably around April, can't remember
And during the summer
I don't have a pic of him now but he's almost back to how he looked in February.
