Blue with brown bleed through would be my guess. Splash bred to pretty much anything produces blue. You've got blue with brown leakage, so I think you'll end up with some leakage.
It might also produce splash chicks now that I think of it.
Splash bred to other colors produces blue as only 1 black diluter....but you've got a splash bred to blue...so 50% splash as 2 diluters and 50% blue as 1 diluter inherited.
