Sadly, I don't believe in magic. But if I did (and if it was a particular color) then I'm pretty sure I would see it as a stunning mixture of turquoise, teal, sea foam, aqua, and ultramarine. These colors have a real magnetism and I find that I surround myself with them. Art, clothing, oven mitts, and, umm, even my sofa.
