I did not know all that about blue. When I bought my house 3 of the bedrooms were painted in blue and 3 in a blueish green. Since I don't have smokers in my house or cook high with any grease the walls are still the same, never had to paint em yet. I like sapphires and topaz and have rings with them in, also sapphire earrings that were given to me from one of my work places as a going away gift. I have blue eyes and I love to wear blue, especially light denim blue or blue Tshirts. I thought pink was the calming color, guess I was wrong and maybe the reason I like blue is because it makes me feel good. My sunroom off my bedroom is blue and my bedroom and en-suite are a slightly different shade of blue. The couple before me, loved blue so only the kitchen and living room are white. My office is a deep color of blue. If I ever have to paint I might stick to most of the colors already here because I haven't gotten tired of them yet and I have had this house for six years already. Interesting that it's a calming color and I like it so much.
