Silly basic color genetics question.

I have 4 bantam cochins..1 black frizzle roo, 1 black regular feather hen, and 2 red regular feather hen. How exactly do color genetics work in chickens? If the black roo breeds with the red hens will some of the babies be black and some be red or will they be another color altogether? I plan on leaving the 4 of them together and hopelly the hens will sit on nests and hatch the babies that I can take out and put in the brooder.
