Egg color of offspring

[caliclucker]

I have a mixed flock of BR, Welsummer, Easter egger, and silver laced wyandotte hens. I also have one buff Orpington roo who does the bulk of the breeding and a silver laced Wyandotte roo who mates when he can sneak by the other roo. I'm curious about the potential offspring of these matings and would like to know what egg color the new hens could possibly produce
