what is the color classification name for these silkys?

[preciouschick]

One hen is buff with a few gray and black feathers on her tail. she is putting out these. The dad is white. the light with the chipmunk back are partridge? What are the gray/ blk ones? they go from really light gray to darker gray with blk wings. the single pictured "partridge" has split wing and so do her sisters of the same colors. (backyard pet quality).
thanks ahead for your thoughts and identification.

do silvers have more of a sheen as they age?
