The main theme is using the moon's texture as a background and uses the original Subsystem's invverted gradient for hue. The hue for each event is Cyan, Magenta or Yellow in that order.
The hue for the first event of this series is Cyan. Everything (posters, tickets, web grpahics, etc.) reflects that.
The next event's theme is going to be Magenta, this is what we project the poster to look like.
