Sorry, I should have been clearer. :)
Let's take a spiky monochrome spectral distribution, move its
main wavelength along the spectrum and suppose it describes a
light source's emission.
My question could be rephrased as "will the perceived blue
colours be *necessarily* darker than the green and red ones"?
As far as I'm aware, there is only one layer of receptor cells
in the retina - all four types of receptors lie next to each other,
though in different concentration in different areas
If I correctly understand the explanation given by Real World
Color Management (second edition, pages 22-24) you're talking
about cones in the first layer while I'm referring to opponent
pairs in the second layer.
Thank you very much for your answer.
