Paint Color for Bathroom-- help!

So our new guest/kids bathroom is white and grey (a carrerra /stauario marble look) -with white fixtures and brushed nickel fauctes etc -- what color should we paint the walls ?

Its a 7x10 bathroom but its got low and slanted ceiling height (its a converted attic space)

I,m thinking soething in the purple family but cant decide whether to go light or dark or in between..

some colors I was considering- all from BM--

Mulberry wine, Wild Mullberry, Tropical Dusk, Lavender Mist, Dreamy Cloud.

Any thoughts or anyone use any of these colors ??

I would probably go with a blue-ish gray on the walls. This is what we did in our guest bath. It's a very soft blueish gray.
