“Golden Light” is the second song on 2017’s EP “3 O'Clock” by the New York band Blonde Redhead. “Golden Light” happens to be the only song on the EP that got a video, shot by Italian shortfilm maker and actor Virgilio Villoresi. In the video description on Youtube there’s an explanation that sheds light on the process of creating the video:

The video features the RGB optical illusion, a device that also Mario Bava used in his horror masterpieces. There are no post-production effects and everything is handmade, recreated live. The illusion takes advantage of complementary lights to show a red, blue or green drawing each time, depending of the color of the light projected.
