I saw these in an example somewhere on the wiki a while back, but never figured out how to use them. Is this a possibility with Dynamic Lighting? For example, right now if I want to give a room a red glow from red lights, I have to manually color it in GIMP, which doesn't apply to any tokens moving through it or assets placed on top. The alternative is a separate asset to act as a "filter", but that comes with its own problems.
