We have a brick floor to ceiling fireplace which is about 8' wide. It is all red brick, dominates the room. Any suggestions on painting it to blend in with bookcases we hope to build on one side? It goes across the corner of the room. I've seen decorators on tv paint with ??? and use a sponge or rag to dab another color. Not sure what kind of paint to use for either part of this project. Would appreciate any suggestions short of tearing all the brick out!
