Frame,splash & tobi . Tobiano just the way white wants goes up the one hip. Frame the solid colored legs are the biggest tell sign.The belly white looks splash but white on one side & neck more frame & the more jagged edges to the white. Blue eyes could be splash or frame.
I personally don't see any tobiano. If tobi was there, the leg white would connect to the body white on that side where it hits the hip. Also, minimal tobiano that tries to cross on the hindquarters tends to head for the tail head rather than the point of the croup. Another consideration is that tobiano likes to leave white in the flank area, as it has in this mare, not take it away as in the OP's horse.
First of all, Paint is a breed- American Paint Horse to be exact, and pinto is a color [really it's a pattern, not a base color, anyway]. Pinto covers frame, tobaino, sabino, splash, dominant white, and I think that's all the pinto patterns...?
No. That site is outdated and uses terminology that no credible person would use. "Overo" and "Tovero" are not correct terms, and are not used in genetic circles ever. The only reason they persist is because backward registries still use them, and people who don't know any better.
