Mexico has a great tradition of public murals. Artists like Diego Rivera, Diego Alfaro Siquieros and José Clemente Orozco left an unparalleled legacy of serious wall art with a social conscience. Their works inspire us.

But Mexican mural painting also has a lighter side, and these works inspire us, too. On a recent trip to the Yucatan, we spotted some terrific public murals, some joyful decorated buildings and some funky do-it-yourself hippie art. Under the bright Caribbean sun, the colors sang out and the spontaneity of these paintings reminded us what fun murals can be.
