Tattoos and Rainbows pays homage to the chain-ring grease tattoo that stains the calves of cyclists. The tattoo is a mark of camaraderie that unites cyclists everywhere. One can discern a cyclist in the crowd by noting signifiers such as the tattoo, rolled up right pant leg and helmet hair, often prompting the exchange of knowing looks and gentle smiles between complete strangers.

The rainbow rising above smoggy clouds refers to cyclists' commitment to making this world a better place by choosing to use a form of non-polluting transportation.   Many cyclists will recognize the ubiquitous colors of the "rainbow jersey" gracing bicycle gear everywhere.
