Color Commons was an interactive public art work by artist collective, New American Public Art. It was commissioned as part of the Greenway Conservancy's 2012/13 Winter Lights series and was exhibited on the Greenway from January 2013 - April 2013.
The artwork allowed the public to change the color of the Rose Kennedy Greenway Light Blades by sending text messages to them. Participants could write any color they could think of and send it to the Light Blades number (917.525.2337) and instantly all the Light Blades would change to their chosen color.
