What color eggs will these isbar cross chicks produce?

[Coletafarm]

As the title states. Trying to figure out what color eggs these future chicks will produce and what to call them for sell purposes.

I'll have 3 isbar roosters (two black and 1 blue)

I know the chicks from the marans eggs will be olive eggers (right?)

But what about the others

I have several light brown/pink layers including Wyandottes, bielefelder, zombie and sapphire splash, pita pinta and bsl
What would you call these chicks? Would they be olive eggers, EE or just BYM?

I also have Crested cream legs bars and olive eggers.
What about their chicks? EEs?
