From hyperphysics I found the distribution of cones by color is "red" cones (64%), "green" cones (32%), and "blue" cones (2%) . Additionally, chromatic aberration causes the blue to be slightly out of focus. However, your brain is more sensitive to the signals from blue cones to compensate but this still doesn't overcome. Additionally, many of these blue cones are outside the forvea which is sort of the high resolution part of your eye. It would therefore seem to make sense to cut the number of blue pixels in favor of more green and red pixels. Not sure what the arrangement would be and you would still want to be able to make pure white. Maybe just replacing half the blue pixels in an RG BG arrangement with white pixels.


Another idea...
I wonder what it would be like if instead of using RG and BG pixels one used three sub pixel types. Something like RedCyan, MagentaGreen, YellowBlue. In this design all pixels would be able to render a perfect greys and 1/3rd the color information. In rg bg neither pixel can render gray but instead render 1/2 the color information. Your eyes have way higher resolution for black and white than color so maybe this would produce a better looking display with fewer sub-pixels.
[never mind, you don't talk about the stereotyped misconception about rods and cones, misread it. I'll just leave it here to lift us up from general ignorance]

Don't be fooled by the rod & cone stuff they teach you in most schools. The general perception that you see colors with cones and black and white with the rods is wrong, period. Allthough the rods have no color sensitivity they are mostly used to see contrast in extremely dark sistuations. The funky thing is, you don't use them above more then minimal light intensities. They are used in situations where color information is almost absend and light conditions are extremely low. They use an amplification system that responds to even 1 single photon. Because of this, even at moonlight situation the rods are way too sensitive. Have a look at some "real" textbooks about the inner workings of the eyes and eyenerves and you'll be amazed about the ingenuity of the organ and the processes that take place inside it.
