I forgot to mention IF you do use color, and IF you choose to ignore my experience and expertise, (J) please, Please, PLEASE make sure you can’t see more than one bright color at a time. For example, this week I walked into a house that had a bright green living room, a blue dining room and a very bright yellow kitchen and they were all visible from the entry way.
If you are a seller, you are asking too much of a buyer to like all three of those colors and like them together. I’m not saying it’s impossible to find a buyer—it’s just that a buyer who likes exactly the same combination as you do is harder to find. Combination is the operative word here—think slot machines!
