Logo for the Circular Europe Network, an EU Program for the Circular Economy for Cities and Regions, supported by ACR+ Brussels, Belgium.
A star of the European flag is subtracted from a circle (circular) and results in an illustration representing a group working together on a project.
The blue color used is that of the European flag.
The concept is: subtraction. The name was created by leaving off the first letter of "concerto". So doing the same in the visuals was an obvious choice.
