I was so stumped when I fist saw the couple. I though to myself, "What color would the foal be?"
So, I went to research. Wow. It is just amazing how detailed all this stuff can get.. so... anyways.:
This girl IS considered a grey, Like her mother, she has a light rose tint to her. Her father on the other hand had the less dominant gene, so he only left her with a slight bit of the champagne color, such as the lighter muzzle, mane and tail tint, etc. He also have her the more sharp sabino.
Ugh... I hope this all makes sense (aka calculated it all right), and I really hope you like her!
P.S: It was so tempting to do edited lines on her!!
