Red Star to Red Star does not tell you what the parents were, other than the mother had silver and the father had gold. There are a whole lot of breeds that have silver and a whole lot of breeds that have gold. Then you have all the other genes that can get involved, sometimes in strange ways. Plus all the possible patterns.
What you would probably get is various shades of red, some dark and some light, plus some chickens that looked sort of white, but probably more of an off-white. And you could get these different shades in various patterns, depending on what breeds and patterns the original parents were. I don't know that I would call them a motley crew, but cetainly they could have a lot of variety. Or if the parents had similar patterns, you might get a few various shades but not many and not a lot of pattern variation, so not really a lot of variety.
