Blue symbolizes: youth, spirituality, truth, peace. Blue is the coolest color - the color of the sky, ocean, sleep, twilight. A pure blue is the color of inspiration, sincerity and spirituality. Blue is often the chosen color by conservative people. Blue is the calming color. Dark blue is the color of truth and moderation. If its blue, it gets posted! Blue has always been my favorite color, COBALT in particular, and Pinterest is just the place to keep an ever changing blue collage. Enjoy!
