When a movie hero leaps into a taxi and shouts, “Follow that blue car!” he takes the driver’s understanding of color for granted. But, physiologically speaking, can we be sure that the hues we perceive are the same? How do you actually describe them? To what degree are they created in our brains? This program explores what color really means to us, with expertise drawn from the realms of neuroscience, evolutionary biology, and art. Shedding light on the role of color in the animal world and how it influences moods and reactions, the film features brain researcher Beau Lotto, who conducts a series of experiments to prove that perception is key. Meanwhile, color-blind artist Meghan Simms prepares to undergo gene therapy in the hope of improving her response to chromatic stimuli. A provocative and engaging report. Contains brief nudity.
