I'm using the 6th shader on the first page (not sure of the name, but you are going through all the cubed hallways at different rotations) When I apply the Hue and Saturation effect, it doesn't shift between all the colors and gets very bright. Furthermore, when adding the Brightness and Contrast effect on top of the Hue effect, the screen gets very bright. I'm on a Macbook Pro 2021.
