Is there a rule of thumb on what color to paint the inside of your homes entrance doors? All the entrance doors are metal. The interior walls are a very light grey (siberian ice) and the ceilings are white...also all the plug covers / light switch covers are white. The trim around the doors are stained wood (pine)and the same pine colored wood is all through the house. I think they should either be painted white or the same color as the grey walls. I NEED HELP!
