The image is blurry but it could be Tramonto Mix

I can't be precise, because this isn't my project, so the best I can offer is an educated guess.

That appears to be a Majestic direct vent fireplace, which is about 33" tall, with a mosiac tile surround about 6" high, plus a mantel header, crown and shelf about 9" high, so I'd guess the mantel is about 48" high.

Or I can look at the wall switches at the left and right, knowing that the electrician likely put them at 48" off the floor, and guess the same thing.

Try Sherwin Williams' Stone Lion, SW 7507 (gray undertones), or Tamarind, SW7538 (golden undertones).
