    Gale,

    This is not that good of an article :) Here is a short list of my diagreements.

    First of all, green channel practically always contains information - even for pure colours it contains data because the filters used are not "pure" green; and above that pure colours in Nature are extremely rare.

    Second, non-retardant demosaicing is restoring luminance, and only then the colour.

    Third, your eye is also doing a sort of demosaicing, as luminance and chrominance sensors in our eye exist separately.

    Forth, human perception is resolving less details in deeper saturated colours, like red.

    Yes, I tried. IMHO it oversharpens saturated colours.

    I also tried shooting resolution target through colour filters to see how resolution is affected.
