Tobiano, frame and sabino.
You can tell she carries sabino due to the roaning like jagged edges around the white.
Frame is probably harder to see but the color will literally "frame" white. Like a picture frame. So looking at this guys neck (left side) there is that random white patch surrounded by color. Thats one example. Aslo the facial white, there is the big block of white at the top and then it tapers down into a stripe. Thats also an indication of frame.
Tobiano does not cause facial white. So anytime you see white on a horses face, no matter how little, there is some overo gene at play.
