What color is she?

For context I am a vet tech at a county shelter (and dog enthusiasts my whole life) so I’m really good at recognizing breeds/coat patterns. My spouse and I are adopting this girl Monday and I cannot for the life of me put a name to her coat pattern/coloring. It’s like something between a Merle and a tricolor? Any guesses are appreciated! And we’re naming her Runa :)
