Behr Celtic Gray - Don't let the name fool you! I so love this color. Very pretty blue/green/gray. It made me feel happy the moment I started painting. :D The color seems to change with the light. Sometimes more blue, others more green but it still looks great. Most beautiful in the bright morning sunlight. I fell in love with this color and painted our entire down stairs with it over 5 years ago, and still love it! I may lighten by half for the bedroom.
