Hey everyone!
This is a small pg that sends different color information to each of your eyes. As this is not something that happens in everyday life, the brain will be confused and create a new color sensation! I was inspired to do this after some research on tetrachromacy, the ability of some humans to perceive more colors thanks to a fourth color sensitive cone on their retina.
You can try this PG with a VR headset:
Or you can just use 2 color filters and put them in front of your eyes if you want the low-tech approach
