My VT100 is most yellow on the side facing the window,

years had ordinary glass. It is less yellow front and back, and
almost no yellow on the side away from the window. Same with its
keyboard.
So, in at least some cases, it does seem to be related to how much
light that falls on the surface.
Yup. I pulled a ITT clone of a AT&T 2500 series desk set phone from the
storage cabinet. You know, the usual made-to-last 50 years iconic
phone. It was a light brownish-beige after I picked it up cheap back in
the 1980s. It has never been used, much less seen the light of day.
Today, the beige has developed an ugly yellow cast--and it's uniform
over the entire phone. The material, as I seem to recall, is ABS (Cycolac).
Oddly, the WE-made same-color phones that I have and are out in the open
(and the same color) don't show this discoloration.
