I am SO happy someone brought this up! I have the greatest names for all different colors!
BLACK & GRAY HORSE NAMES: I like Xavier, Thunder, Lightning, Smoke, Midnight, If you want all names, these are names I have for dogs, but you might like them! Bolt, Shadow, Carlos, Elliott, Jet, & Commander.
WHITE HORSE NAMES: Gabriel, Jet, Zippy, Zipper, Handel, Bach, Cloud, Mozart, Stream, Moonbeam, Cliff, and Snowy.
It all depends on the colour, personality and breed of your horse, for example you can't have a jet black horse called snowy, nor a white called kaspa. Bay horses dobby Fudge Toffe Soldier Jazz Fantastic (fanta) River Dancer
