If you have a token with an aura you can "change" the color of the lighting. (Someone just suggested now to use an invisible token, which I never thought of) It works great, but the token needs to be on the token layer, as the aura is not visible to the players on the lighting layer. If we could have a way to adjust the color of the lighting or have the aura visible on the lighting layer, that would be great! Less tokens to click around on the map! Another issue with using the aura is that auras go through dynamic lighting walls, so it bleeds into other rooms if you're not careful, Also if the token is offscreen, the aura color disappears from the screen.
