Grays

We are moving forward and almost under contract for the renovation. I'm supposed to pick out kitchen cabinets this week and their arrival date will determine all of the other work. In the meantime I've been picking up/out finishes which I'll share room by room in another post. This post is about paint color. Who knew there were so many grays!? What do you think? We are looking for a darker gray for the master bath and a lighter gray for the master bedroom. The white tile in the pics will be in the bath, but it's really just a point if reference. The samples are painted on a tan wall.

The first one is Granite Boulder followed by Dolphin Fin, Silver Drop and Irish Mist.
