I have had a flea bitten grey, a chestnut and a bay horse. Natalie's first pony was a chestnut paint mare and of course you know that Gracie is currently a dapple grey.
I tend to love dapple greys but you can't go past the shine of a chestnut! Allie has some awesome dapples at the moment so a dark dapple bay is a fav of mine too. I don't think I could pick a favourite! I know I'm not a huge fan of leopard appys, or cremello or other dilutes.
As long as the horse has a shiny healthy coat, it makes any colour look good.
Below are three healthy, shiny butts on a recent trail ride (which I need to blog about!)
