Geng and colleagues studied the effects of light color on employee decisions. They found “that blue light more likely promotes individuals choosing the farsighted intertemporal option (i.e., delayed but larger payment) than red light. . . . The current study demonstrates the effectiveness of light color and provides a solution to nudge people to make farsighted choices.”
