I would paint the entire fireplace including the mantel, all trim and shelving white. I like the Whisper White, but you must bring the paint samples into the room to see for yourself. The sheen on all woodwork should be semi-gloss, easy cleaning and looks crisp. I agree with painting the walls and I would paint the part above the mantel the same color as the walls, Summer Hue is beautiful, but once again I have no idea how that would look in your room. The walls should be flat most brands make a fairly easy to clean flat. If the fireplace were the focal point of the room, it could look very cool and dramatic to paint it a very dark gray almost black. But at least in this picture it seems that the entertainment/shelving unit is the focal point. hmm .... better stop while I am ahead.

thank you very much to everyone who responded! I'll look into espresso and charcoal grays. As well as the steel backplash. Emmarenes, I'm living abroad in India, and the only granites in my budget are the local ones. I was advised against the gray and white local ones because i was told that they would not hold up well in the kitchen. I could have gone with a black galaxy as well but i have that granite now and despise it because of the way it hides ants and bugs so well. we live in a tropical area and there are always critters here and there. My first choice was a Brazilian white granite but it was triple the price. This granite is called Shiva pink, so it has a pink salmon and gray look to it. Im really hoping I don't hate it once it's installed. The stoneyard was a 9 hour trip up and down and i was just pressured to make a choice after several undecided trips. And I'm getting new cabinets put in. but I think I can wait for them to put the slab before staining the wood. Thanks for that idea :)

If you will like to go little different than Indian / traditional one, mint green colour is in trend and goes well with brick colour walls. Looks good if you have white appliances, crockery and some other elements that are visible with it. (Sourced from google images) https://goo.gl/images/Wyu1kR

this is looking good. finally someone on houzz has listened! Thank you. I would leave it as it is since any items you place up there needs to be maintained and that is one more task we would be adding to the lady of the houzz. but if you are still wanting to add something for that first client impression may be few large glass pickle jars or just two of three colourful glass sculptures. as would perhaps know - less is more in modern design.
