BM shoes

My BM's are wearing Euro Gray (like a shimmery pewter). I don't want them to spend extra money buying and then dyeing shoes. Would a regular silver go okay with the darker grayish silver dress? I figured this way they could just go buy silver open toed shoes which will probably be easy to find come spring. But I am just not sure if it will look right.

Also, my junior bridesmaids are wering a light lavender color. Would silver shoes go for them too?

By the way, the main colors of my wedding are silver and lavender.
