Congrats! Glad she turned out fine. She's a good example that breeding two frames won't give you more color.
However...good Lord those people should not be breeding horses! If you don't understand basic color genetics, think you can get a grey out of that combination, and risk the life of foals by breeding two frames...breeding is not for you! And the stud sure has some upright rear pasterns. Looks to me like their purely a color operation as I don't see anywhere where their horses have proven themselves.
