    LOL. I'm presently reading a medieval mystery that involves a discussion of Nominalism vs. Realism - it sounds just like that.

    I understood what the OP meant. I was making a point to the others failing to distinguish between various substances and finishes.

    Actually, being green is the inherent quality of green. The wavelength we perceive as "green" may also be vert, groen, zöld, etc. But at least for English speakers, the defining characteristic of "green" is that it is green.

    Well, meanwhile I got intrigued by this topic and re-viewed my collection. And I have to admit that the matted chromium and matted anodized aluminium surfaces could be distinguished in specular light, with the former having more gloss.
    But with much more surface treatments employed nowadays in the process of anodizing this may not apply any longer.

    chrome-nose canon fd

    I had a chrome-nose, single-coated, Canon breech-lock 28mm f3.5 along with my first (1977) Canon F-1. It was a wonderful lens with a special affinity for Kodachrome. Handsome, too.

    I prefer black
    Less blingy
    Later Zeiss were all two tone aluminum and the exposure aluminum gripping area shows wear quite easily

    Some old aluminum lenses were polished and lacquered, which looks very nice. But when the lacquer wears, the Al tarnishes to a dingy grey.

    Under natural light aluminum, chrome, and nickel are easy to distinguish.
