If you still ignore my advice and use a lot of color, and you use different colors in spaces where you can see all the colors at one time, you can still make a sale a bit easier if you choose colors that are related.  So instead of using yellow in the kitchen, green in the living room and blue in the dining room you could use yellow in the kitchen, a gold in the dining room and a brown-gold in the living room.  This way the colors are all in the same family. You’ll still lose the buyers who don’t like the colors in that part of the color wheel but you might not lose the others.  I’m really trying here, guys.
