What colors of chick down indicate black chicks?

[saysfaa]

If I were to try picking chicks out of a bin of Easter Eggers or Ameraucana, what colors could grow up to be black?

I know what color Australorp chick down is, do all chicks with that color pattern grow up to be black?

They're usually black on top and a creamish color on bottom
