Thanks it wasn't done on purpose its just the paint I picked out and when we got home I told my wife I couldn't believe I had picked that particular color. When she asked me what color I wanted while we were at the hardware shop I told her something in a green or blue and Oh well there it is. That is my music/bike room. I've since put the floor down and it looks like steel diamond plate its pretty cool. Nearly soundproof with lots of insulation in the floor and walls and ceiling. Its in the basement so I raised the floor with framing by 2 inches and laid in styrofoam panels in between.
