The campaign’s key visual element is its red speech balloon and well-known three-part phrase “be …, be …, be berlin.” These two elements are already familiar sights in the city and can be found everywhere be Berlin is active, i.e. on posters, brochures, stickers, t-shirts, etc. A red rectangle provides the framework for the three-part phrase and symbolizes two major elements: the inward messages of the campaign’s “ambassadors” and the external effect of these messages. Although it has a rectangular form, the red speech balloon is nevertheless a well-rounded feature.
