Color Shade Question

[Rhorsegirl80]

I have a question. I am sort of confused about this. Whenever I send my horse to training it comes back this lovely shiny color. Is it the training that does it or is there a special thing you must do? Or does it depend on the dam and sire?
How do you get a horse from being dull and not fancy:


To being all shiny and fancy:

There are two different shines currently in the game and can be achieved two different ways.
The one you're talking about is muscle-shine, that happens as the horse is trained up.
The second is metallic and is a genetic trait attributed and actually found in real life Akhal-Teke horses:


You can find this shiny metallic gene in the Turkmene breed in the AC. It is a dominant trait and will also display a shine from very gentle to very pronounced. You can tell the difference between muscle shine and metallic shine by looking at a shiny horse's face. Muscle shine doesn't affect the horse's face, whereas metallic shine will.
