Hmm, they are not quite identical after all.

I thought I would do a side-by-side comparison of your v3.6 assumed_gamma 1.0
version to v3.8xx (I changed the "skies.inc" pigments back to their originals.)

There's a definite difference; I assume that it comes from the many
'under-the-hood' changes made to POV-ray since v3.6.

So it seems to be very difficult to determine (and update) what the author's
*original* visual intent was for these pigments.

Unless we all go back to using v3.6  :-O
