Two questions about color

[QueenPeppermint]

This hen is Frankenstein. She is a buff Orpington x blue langshan. If we were to hatch eggs from her next year and the sire was white leghorn x welsummer, would the chicks have coloring similar to her?

I have two little roosters with this coloring. I can't figure out what their coloring is called because they're too dark to be ghost but too light to be any of the other grey coloring patterns. Cross is either barred rock x leghorn, barred rock x unknown white lightly feathered feet barnyard mix, or barred rock x leghorn mix.
