Color models always involve engineering tradeoffs because human color perception can involve: 1. The human perception of particular colors involves negative response in the cones. You can simulate this mathematically, but you can't reproduce it in a gamut. 2. Some humans have tetra-chromatic visual experience to the point of awareness. A larger group have tetra-chromatic visual experience that is measurable based on their response to testing. 3. Scientifically there is nothing different about the "visible spectrum" beyond anthropocentric interests and our experience of it is based on adaptation to particular survival events, not on theory or mathematics.
