1) 3/2/26, around 9pm, Playhouse
2) the lights on the Syc in the back of the stage (basically a big sheet that spans across the entire back of the stage that is there for light specifically) that goes from blue to pink, shifting in color from the ground up.
3) The light is very pigmented and bright, as actors walk slowly in front of it all you can make out is their silhouette. It fits the scene beautifully, and gives the actors an unsettling and mysterious presence.
