Blue is the safest color in the book across it's entire shade range, goes with anything, and doesn't clash with anything. And is one of, if not the most, popular colors in the world. Which is why I can't wait for someone to do a CCnB (or better, a STARK WHITE and blue) full set. I might do one from SP out of impatience. Just can't decide on shade. Would be nice in baby blue, royal blue, or dark blue.
