Mindful Grey by Sherwin Williams. It is such a peaceful, calming grey and with pink accents it is fabulous.
I agree you need the right Grey without too much blue.. Try Benjamin Moore's Abalone, Pale Oak & Wish. Those a re grey's that fly under the radar are beautiful and very soft & pretty.
Just did my daughters room pink and grey...the walls are pewter...
Dolphin by Martha Stewart (available at Home Depot)....it is beautiful!
