I'm having an issue and I can't figure it out. I want to add a global effect to the entire display to ramp it down using an intensity layer. When I add a Pulse or Set Level effect it will only allow me to select from a list of discrete colors.

I'm thinking its due to the fact I now have incans in the display. Do I need to create a duplicate effect for each color now? Is there a way to apply global intensity regardless of the color or light type?
