A paint job that I'm satisfied with very much is our kitchen. Unfortunately, I have no "before" pictures of it. The kitchen was originally painted your typical white. Then, I painted it a pale yellow. But the colour I really wanted it to be was a red-orange. So finally, after a year of living with yellow kitchen walls, I went about finding the right shade of red. I paid a little visit to Home Depot and got a bunch of paint chips. Then, I put up on the wall the top four I liked. For a week I observed how the paint chips looked during various times in the day and finally made my choice. It's Behr Premium Ultra Plus in Carmine Red.
Red is supposed to whet your appetite. I also find it to be a very stimulating colour.
