Applejack's coat color and mane matches to the Palomino well.



As for the Equestrian pony sizes, they range anywhere to Pound and Pumpkin Cake (the foals of Mr. and Mrs. Cake), Flurry Heart (The foal of Shining armor and Princess Cadence) to the CMC (young school age ponies) to the adults (Mane 6) and even the older characters like the Cakes, Mayor Mare, and Grand Pear as well as Granny Smith.





You have Saddle Arabians, Trouble Shoes, and of course Celestia and Luna.
