Spooky negative light (Patreon)

Just something cool that came up mid-production. This scene is lit with a soft blue light, but I made the intensity of the light oscillate up and down (just imagine a flickering light). The intensity of the light unexpectedly went into a negative value, somehow causing it to REMOVE blue from the scene instead of adding blue to the scene. This hellishly aesthetic color scheme is the result. Here's what it's supposed to look like: https://i.imgur.com/kJaxSXn.jpg (I also attached the original to this post)
