Thank's Terry and C.Dd, for you always enlightening replies.
What strikes me, though, is that when I look at the light outside of my
studio right now (1:00 pm) I don't have the impression that the light is
that yellow? And I know for a fact, for having measured this light over and
over so many times over in the past, that this light is unlike 6500K. In
fact it's always between 5200K to 5500K. I know color is next to impossible
to relate acurately in words but the color sensation I am getting from
starting at at white surface lit by direct sunlight right now is not as
yellow as Photoshop would have me believe by converting absolute
colorimetrically a D50 Lab 'white' to a D65 'white'. And no, I have a
Munsell FW-100 hue test here and I am glad to report that, despite the
coutless hours I have torn my eyes looking at jobs and retouching images in
Photoshop on a CRT in the past, I still enjoy a normal color vision.
