Subject: [Leica] Black Anodizing

LUGers,

I have a few lenses from the mid 70's (both M & R) that exhibit two
different tones of black anodizing. One black seems to be neutral and
black as it should be, but the other black has a reddish tinge to it.
Especially noticeable in sunlight or under incandescent light. Can
anyone explain this phenomenon? Just curious.
