Black split to blue???

How do these genetics work? If I have two black split to blue orpingtons ( a roo and a hen) what color off spring will I have? I would assume all black...? Trying to understand what that truly means. Thanks!

It doesn't work like that. Black can't be split to blue.
If a bird with any black has a gene for blue then its blue. Blue can't hide sight unseen on a bird that has black.
One copy turns black to blue and two copies turns it to splash.
Black can be split to lavender sometimes called self blue. In that case two split birds bred together would produce on average 25% lavender, 25% black and 50 % black splits.

Okay, that makes sense to me. Thos guy was advertising black split to blue and I had never heard of that (not that I know a ton about genetics) so I wanted to check up on that. I did buy one of his blacks bUT I had a feeling it wouldn't work like that. Good to know... ThanKS for replying!
