I am working with After Effects and I am making use of the Venetian Blinds Transition. I applied the effect to an a few adjustment layers create a reveal transition on some still images. The problem that i am facing is I don't know if I can change the color of the spaces between the transition. I wanted to add a blue ramp sort of color. Does anyone have any recommendations on how to resolve this? I included a video of that actual project composition, as well as an image of the project window for reference.
