The only part of this “show” I remember is a boy letting his male friend into a room and followed in by a girl, I don’t remember clearly what colour paint each had on but I’m sure one was in blue and to leave the room they had to mix the pain on their body to make a colour so they could leave. They both looks confused and realised what they have to do so they helped each other out.  This is the only memory I have I just hope it’s helpful.
