Bob,
Call me nuts, but I'm actually looking forward to the day I'll have a
cataract removed for the very reason you mention, that experience of
looking at the world, all of a sudden, *without* yellow filters. I read
the same account as you described, in the color literature, that the sky
takes on a stronger vivid shade of blue and so on.
All I know about the Standard Observer is that it was made of two groups
of men but I have no details on their age... I guess they had "normal
color vision" 😊

Many people don't seem to know that the lenses in the human eye start
going yellow with age. By the age of 50 most people are looking at the
world through yellow filters! I experienced this when having a lens
replaced because of cataract. The new plastic lens was clear, and when I
came out of the operating room, I could see that the dresses of the nurses
(that were grey/white stripes before) were now blue/white when I looked at
them with the new lens. With the yellow lens in my other eye they were
still grey/white! A blue sky was now qite vivid with the new plastic lens,
not so with the old yellow lens. I played about with Wratten filters to
see how yellow my original lens was, but sadly I can't find the details
any more, and nnow have two clear plastic lenses. I wonder how old the
'Standard Observer' was?
