Sue's image is a V. cornuta type but which one!
I came across VIOLA CORNUTA SKIPPY BLUE YELLOW which is close!

There is a Viola cornuta x Fun Eyes Tricolor which it could be, that's a name and not a subspecies but there's no photos anywhere.

Joy has a V. cornuta Bowles Black, the rest I suggested moving to V. tricolor. Maybe Sue's should remain until a name is found for sure, if ever! There's always new ones coming out.
