You could go a long way by specifying the reflectiveness over the visible light spectrum and then do the same for light sources. That way, you could do GDR style truly monochrome sodium vapor lamps, which makes telling colors apart impossible.
To do neon colors, you would need some sort of frequency redirect in your texture data as in "this pixel absorbs 80% infrared, but reemits it as visible red". Then you could have black light light sources and cool poster textures as well.
I think doing textures in this format would take too much space, but doing a 256 color palette that way might be fine.

- RedNifre 2mo agoOh, interesting. So do all neon colors reflect ultraviolet as visible light? Would a neon color that reflects IR as visible be possible? Or is it already figured out, but more expensive than UV neon paint?
- numpad0 2mo agoKeyword recalling from a word in GP comment: photon downconversion is relatively easy and used widely, used in LEDs already, but upconversion require more exotic compounds and their efficiency is magnitude worse. Possible but not yet useful. It's certainly not like just using Lithium instead of Neon.
