Museum fatigue is a real thing and Snohetta, designers of the San Francisco Museum of Modern Art’s new 10-story expansion, uses the restrooms to activate visitors’ senses and inspire them to explore another floor of the nation’s largest museum of modern and contemporary art. Each floor features a different, eye-popping color in all of the men’s, women’s and all-gender restrooms. From brilliant green, deep purple, shocking pink, aquatic teal and even SFMOMA’s signature shade of warm red, the restrooms are works of art unto themselves. Insider tip: look for the green flash after exiting the red restroom on the second floor – a classic example of afterimage using complementary colors.
