So I have a Grulla Nokota horse filly named Spirit. My mom and I cannot figure out wether she's a brindle or a roan... She has shoulder bars and zebra stripes on her legs, and a dorsal stripe that also runs directly under her stomach. She has the roan/brindle on her neck, barrel, and rump. It seems to kinda fade in and out a bit depending on the time of year.
I am new to this and am not sure how to post pics, but a while back I made a video showing her and her colour, so here's a link to that.
