Who paints their entire inside of their house the same color?  We have been painting most of the inside of our houses two color coordination. I am considering doing a light cream of some kind for ceilings walls baseboards etc. The thought is once we mask it off we can make some serious headway with a paint sprayer. These are not flips these are properties we are going to keep in our rental for folio. Who all uses one color and what is the color you recommend?
