Hi there, I'm trying to build a patch that will remove luminance info from an incoming video stream, leaving only color data.

What I've done is take the incoming video stream, convert it to black & white (jit.rgb2luma), invert it, and then add it back to the original stream.

Adjusting brightness/saturation/contrast gets something close to what I'm looking for, but not quite there yet.

Any suggestions on a better way to do this?
