A lot of us, it seems, pare our summer palettes down to blues, whites and the tan-to-brown spectrum. Classic nautical. Easy to safely combine, which is particularly welcome during the travel months when you want everything in your bag to work with everything else. It is possible to make the palette a little more interesting, though, by mixing navy and a medium blue. As is the case with most lower-contrast combinations it's a bit more sophisticated, and requires enough disparity in brightness so make it clear that one fabric isn't a faded version of the other.
