Arrows, I think we might have read up on the same stuff because that's exactly why I thought she was rabicano too! Though I also looked up sabino, and that also makes sense (especially with Bliss's huge blaze and leg markings). Ayy, that mare loves being complicated hahaha.
I went out to see her today, but the sun was setting so the lighting wasn't great for a picture. I'm going to see her first thing tomorrow though, so hopefully I can get a good one!
Thanks all of you for your help!! And thanks for the compliment Arrows, she is very pretty indeed (not biased at all).
She's got that expressive face and definitely got the Arab personality haha!
