We could even go up to 2x64bit floats for even more definition... Wait, that didn't make sense to you as a trichromat? Neither does your suggestion to a tetrachromat. For them color is a four dimensional space (tetrachromat literally means "four-colorist"). The RGB cube becomes a RXGB hypercube. You can't emulate X with RGB like you can't emulate green with red and blue.

That will heavily depend on if the extra primary actually allows you to sample something significantly different from the other three or just gives you more color differentiation. My understanding was that human tetrachromats had their extra primary close to one of the "standard" ones and that gave them more color differentiation but not exactly extra colors.

  It gives them more color differentiation in the same way your trichromacy gives you more color differentiation than a deuteranope.
