It was weird, every photograph seemed different because of lighting/weather conditions. Personally I thought it was funny watching people get so het up over it.
Colours (or colors) have always been a good subject for lively discussions! Like many from us, my background in aviation started with the plastic models from Frog and Airfix. Mainly the single engine fighters as I couldn't afford much more. Humbrol was the only model paint available, so their green 66 matched the German RLM standard, the British BS381 standard and the American ANA standard without any problem.
Looking back, the problem must have started when Humbrol started their "authentic" ranges and their "authentic" olive drab looked different than Tamiya's version of the same colour.
People who base the "authenticy" of a colour on photographs must be young or have a short memory. As old people (like us) still know that Fuij-film makes blue-ish pictures, AGFA film makes orange-ish pictures and Kodak often looks yellow/brown-ish (and what about Ilford?). But today you have to explain that there was actually already an analogue camera, before the mobile phone was invented.
I love to do research on colours and in most cases I like the discussions, but personally I don't see any reason to try to convince somebody, who doesn't want to be convinced.....
