To start with, the human eye does not actually see red, Green, Blue.
The vast majority of humans see Blue, Yellow/Green and Yellow/Red - the latter two are extremely close to each other and very wide-band (low purity) receptors, while the blue is very narrow (high purity).
- This is partly why Blue LEDs look so bright at low power levels.
Some women have tetrachromancy, and have a fourth colour receptor as well.
At low light levels, there is also a 'brightness' receptor that has yet another curve - this is usually completely swamped, but becomes important at low brightnesses.
Sharp have done a lot of work in converting YUV and sRGB into their new five-colour system, and it will be very interesting to see the real result.
