Yes, fireplace has gone white....I know you're all wondering about that! If you have outdated brick and you are not going to replace it, my advice is to paint it. You'll need to get the primer on there pretty thick (meaning a couple of layers). Of course, it is recommended to use oil-based primer, and of course I didn't. Brick soaks up paint like a sponge, but I wanted the texture to show through because I am primarily doing my dining room in neutrals. So I used a water based primer and a thin, shiny paint. I love the way it turned out.
In case you wanted to know more about that painting, my grandmother did that for us as a wedding present. It's the view from the window in the room I had at my parent's house.
