And Tiger! - Dusky Blue is recessive to Tiger! - Powder Blue. It's a good pull by the toyger caramel, getting the Dusky Blue out from under the Powder.
Congratulations Lady Stromfield on what I think is your first proof, yes?
Tiger! - Dusky Blue is recessive to Foxie - Cocoa Cream.
I'm not sure if this helps, but I think that my Ocicat - Ebony Silver is dominant over Tiger! - Dusky Blue

I'm going to put the two babies back together and see if Dusky Blue pops out, but this is my supposition right now.
I think your two Oci Ebony and Silvers are excellent tester boxes. Personally, I wouldn't put them with each other. I'd use a more recessive puller and try to get the hidden out from under one of them and then test the next one the same way if the first doesn't hide the dusky blue but rather it's hidden. Good luck!
Tiger! - Dusky Blue is dominant to Balinese - Cream Lynx.
... and recessive to Maine Coon Plush Calico
Roschelle is a Tiger! Purple Kiwi that hides Tiger! Dusky Blue.
The proof that she hides dusky blue is a little bit fiddly.
She partnered with Engres, an Australian Mist Lilac Marble, and they had a Dusky Blue kitten.
The Dusky Blue definitely came from Roschelle, because Engres has been proven on previous pairings to be hiding Tiger! Turquoise:
Roschelle is partnered with Kirwyn, who is Ocicat Ebony Silver. They have an Ocicat Ebony Silver kitten:
Ocicat Ebony Silver can't hide Tiger! Purple Kiwi, so must be hiding the Dusky Blue.
Big thanks to Ivy for the loan of the Dusky Blue for testing and also the Ocicat Ebony Silver boxes.
