I think red makes you angry and then your blood pressure would go up, but green or blue would make it go down, so stick with the calm colors, that's what I try to do, painting the inside of my house with pastel kinds of colors really helps me stay healthy, I had someone help me do it and now I'm going to get a Feng Shua (sp?) make it all balanced, my home must be peaceful and pure because that's what I want to be, too.
