Not exactly. The eye actually has RGB *and luminance* sensors. That is,
three narrow spectrums and one broad spectrum. The R G and B sensors overlap
in their sensitivity range, but in low light, peripheral vision or during
hypoxia the color sensors are not available at all.
There are other complexities, but you probably know that.
At any rate, my point is that there is more to archiving an image of a
precious document then the depth of RGB intensities.
