Blacklight effects would be neat to see.

I wonder, for monochromatic cases like the sodium vapor lamp and the cyan light, if you could get approximate good results by roasting the primaries, doing RGB, then rotating back

So if the problem with sodium vapor is that RGB thinks it's red plus green, rotate it until it's pure red, rotate the materials too, light everything, then rotate back.

Maybe that is mathematically equivalent to existing real time color correction.
