Silo 468
After spending 30 minutes in the all-red interior, visitors exiting Silo 468 will perceive complementary and contrasting colors—such as the blue water and sky, and the green of nearby trees—as more intense, designer Tapio Rosenius says. At midnight, the deep red hue seeps to the silo’s exterior when, for one hour, the surface is awash in red lights, a reminder that the silo was once an energy source.
