I am absolutely loving this; just started reading! I'm in the second chapter (I think) just after the tournament, when you go to visit your horse. The horse is described as "chestnut" but she also has a "black mane." FYI, this would make her a bay, not a chestnut! To keep it consistent, you could just describe her mane as "red" or simply call her a bay mare instead of a chestnut.
