I would paint it white, not just whitewash for a sleeker look.

Paint it dark gray. Doesn't work with your style now.

Love the rug very nice. Good job.make sure FP is 2 shades darker than walls. By the way what is color of walls.? Love it. Maybe one day you can dry wall it and put in stacked stone in the blue gray colors. That would WOW the rm.

Where did you get zebra? Like it over sisal rug nice idea.

Add some white birch logs in firepl. Then add a gray basket with the same logs on hearth.

Also, you don't need candlesticks on mantel to cluttered mirror stands alone.

Thank you so much! Such great feedback! Paint color is from Restoration Hardware... Thinking it was called slate(not sure, though). The zebra rug I purchased on eBay.:)

whitewash would look beautiful

Charcoal gray painted on the brick.

This example is a BM texas leather. Ties in with your decor and it will make your mirror pop!

Charcoal gray, masonry paint in semi gloss. Slate seems to be the deepest tone in the rh slate series besides obsidian - too dark. Test sw garret gray http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6075-garret-gray/ / bring home lots of gray chips to see what has the same undertone as your slate.

Graywash is a neat eclectic or cottage technique but your decor reads modern so a deeper solid is best.

you could just paint in the arch of the chimney breast

Funny, I usually love red brick and usually think to leave it alone, but in your room I really think it will help tie the whole room together if you paint it.

Love your room!! Definitely paint the fireplace.

A white painted fireplace looks fresh and will really brighten up the space! Here is a picture of a living room i just finished where we painted the fireplace white and the clients love it. Best of luck.
