1988 Chilean presidential referendum

The No campaign's rainbow, Chilean plebiscite on Pinochet's rule, 1988 Campaigning to end Pinochet's military rule, the opposition chose joy over anger. A heavy black NO sits tucked under a sweeping quarter-arc of colored bands, and each party backing No had its own color in that rainbow, so one emblem quietly showed a whole coalition standing together. Paired with the slogan Chile, la alegría ya viene (Chile, joy is on its way), the bright, optimistic look broke with the grim visual language usually expected of resistance. No won with 56 percent of the vote, and the rainbow remains a textbook case of coalition branding.
