There isn’t really a reverse EnChroma. The mechanism of color perception is you have three different chemicals in your eye and each of those chemicals reacts most strongly with different wavelengths of light. This is a chart of those three response curves: https://upload.wikimedia.org/wikipedia/commons/thumb/0/04/Cone-fundamentals-with-srgb-spectrum.svg/1280px-Cone-fundamentals-with-srgb-spectrum.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/0/04/Co... The way you perceive “green” is that your brain goes “ah, S is at 10% activation, M is at 80% activation, L is at 50% activation. That’s green!” Colorblindness is when you take one of those curves and shift them closer to the other (shifting M towards L is the most common, shifting L towards M is the next most common). The bigger overlap in curves is what makes those colors not contrast. EnChroma glasses work by blocking a certain wavelength of light that’s right where the overlap is strongest. Maybe you could get the effect of “reverse EnChroma“ glasses by having light at the overlap added in to whatever you’re seeing?
