Pushing the envelope of pixel peeping. Yes, you can even check out the spectral behaviour of those Bayer arrays. Check out the last section:

Now, why are the Red pixels so active in blue wavelengths and yet the color rendition of a standard 1Ds is still very decent?

Because the spectral response of the sensor is shaped to represent a linear combination of the human cone sensitivities and the XYZ matching functions, respectively. At least that should be the design goal: http://www.outbackphoto.com/tforum/viewtop...hp?TopicID=1929

Don’t worry, such overlap finally speaks for a large gamut.

Greetings Samir ! Fancy meeting you here !

Doesn't human vision have such a "second hump" ? Two camels and a dromedary - or is it the other way round ?

Seems that the leakage of one color into another color's pixels depends on the camera model. The 20D is quite different from the 1Ds. I have added more data on a modified 20D, with its UV/IR blocker removed for astro use, bottom of:

The Infra Red also picks up different colors depending on wavelength. A color bar extending from 4000 to 10,000 Angstroms is shown.
