I have used Benjamin Moore Revere Pewter and it is beautiful. It is light enough to go with your gray. You can view it on line but best to get some and try on your walls. I used it through out my remodel.

How contemporary vs. classic do you want to be? Shimmery silver grays would be nice at night, but make sure you have lighting on dimmers. . . deeper will make it tough at night. Test bm metallic silver http://www.benjaminmoore.com/en-us/paint-color/metallicsilver#ce_s=silver
for contemporary . .
consider art with white and orange in a graphic element . . bright orange ribbon trim on a white roman shade hung high . . .
for classic . . black and white art photography print in silver frames
