We recently painted our kitchen a light gray. It was tan to begin with but needed new paint anyways. Our shelves were green before, and I was ready to get rid of that color!
I added a new table (thanks Mom!) for a breakfast/sitting area. I think the gray color really lightens up the room. Still to come are some new chairs for the table and possibly a coat of paint for the table as well.
I said Part 1 - later, Stuart and I would like to lighten up the color of our kitchen cabinets. And then if we win the lottery, I would like to rip up the floors (not the hardwood ones) and also put in new counter tops! That will be Part 2 someday.
