I covered up my fuse box in the basement, I used magnets and decorative tin tiles. I painted the brown tiles classic brown (BenjaminMoore) and rubbed some black glaze over the grooves to make them pop. the silver tiles are just the way they came, and the green flower is also a magnet.
I am loving the difference this makes in my basement with the gray fuse box hidden. (and yes I know the wall is still white. any paint color suggestions?)
