As a color, pink has been hot for several years now, from the so-called millennial pink of a few years ago to the “Barbie” pink of the upcoming movie. In terms of impact, though, one might never see the color in the same way after watching “Chile ’76.” Referenced in the movie’s mise-en-scène (wall color, cake frosting, etc.), via light filters, and even the title sequence, myriad tones of pink denote danger, uncertainty, and vulnerability, conditions that match its depiction of Chile after Pinochet’s coup.
