Some summer afternoons the sun beats down so relentlessly that white is the only acceptable color—to wear, to eat (hint: gelato), and to cool off the walls.
The Greeks get that right, with whitewashed walls that reflect light and keep interior temperatures comfortable even under a hot Mediterranean sun. Here's a simple recipe we spotted for making your own whitewash that may revive limp spirits enough to get you thinking about adding a dash of blue to the color scheme. For step-by-step instructions, see Greenchicafe:
