I started by reconstructing an experiment by Maurice Merleau-Ponty in his Phenomenology of Perception. This box with two eyeholes has two compartments, one for each eye. The left eye is looking into a poorly lit white compartment, while the right eye is looking into a well lit black compartment. The optical result is that each compartment is seen as a somewhat neutral gray and therefore evens out into one gray visual plane.
Next to it I made a color wheel (which was quite a throwback to high school!), which I then photographed and projected onto itself.

My expectation was that I would find some quirky color theory stuff happening with the mixing of additive and subtractive color (light and paint). Much to my surprise, it actually behaved in a largely subtractive manner (with the exception that adding like colors of different values the saturation seemed to be enhanced regardless). Though seemingly not quite as exciting as I hoped, it actually proves quite promising because it means I can follow the normal rules of subtractive color mixing. Therefore, projecting a color onto its complement does indeed, when calibrated correctly, yield gray.

So, by projecting or painting the background gray, I could then project a color onto its complement in order to gray it out and make it disappear visually.
Here are some short clips of my tinkering:
