What can a red nose do? It can build a brand. A red nose is the visual hammer for Red Nose Day, a campaign started in the U.K. and has now moved into America. The Red Nose Day fund is a program of Comic Relief, a non-profit that raises money for children living in poverty. Hundreds of charities do similar work, but most don’t become as well-known or raise as much money. The difference? A visual hammer that drives the brand into the mind. It might be a simple or silly thing like a pink ribbon, a yellow bracelet or a red nose. Three visuals that have built powerful, relatively-new non-profit giants.
