My fireplace is tan...gee I don't know..rock? Weird brick? To me, it's an ugly tan boring thing. Do y'all think so too"? What could I do? Leave it? Whitewash it? Can I stain it? Didn't really want to "paint" it, just jazz it up a bit. Whe walls are "pale moss" green, it's called Koi pond but that doesn't help. Thanks!
