A spectrum describes the physical properties of light, color describes the perception. Colorspaces are about quantifying the perception of light as observed by most human beings.

You run into interesting problems of metamerism https://en.wikipedia.org/wiki/Metamerism_(color) https://en.wikipedia.org/wiki/Metamerism_(color) particularly metameric failure. For instance there are those RGB lights like Phillips Hue and Lifx which would render colors in the environment better if the colors were wideband but would work better at rendering strong saturated colors (like a display) if the R, G and B were laser-like monochromats. There was this system for stereo films https://en.wikipedia.org/wiki/Dolby_3D https://en.wikipedia.org/wiki/Dolby_3D that exploited metamerism by using 6 monochromats and very glasses with narrowband filters that route 3 of them to each eye. These were very high performance but were crazy expensive (needed theft protection) and got trashed in the marketplace by Lifton's RealD system based on circular polarization even though RealD doesn't perform quite as well.

  The band filtering glasses type 3D is used today in a lot of theme park rides, like Avatar Flight of Passage for example. https://variety.com/2012/film/news/transformers-ride-pushes-3d-boundaries-1118054451/ https://variety.com/2012/film/news/transformers-ride-pushes-...

    These were withdrawn from the market for Cinema in 2018 according to Dolby https://professional.dolby.com/product/dolby-cinema-imaging-products/dolby-3d-bundles/ https://professional.dolby.com/product/dolby-cinema-imaging-... but there might still be some theme park rides still using it.

      In my experience many theme park ride seem to use them. I have looked at the glasses for rides like Transformers in my link, and Avatar and Harry Potter Gringotts and none of the lenses were polarized to my quick tests.
