Well that's the thing not saying it isn't genuine but really not a=all that vibrant, and sort of the pastel character of colorization. Particularly would seem the warning yellow in that arm band should be much more vibrant blaring if a true image vs just matching the over all image saturation.
But on a side note, still color well preceded single process (not Technicolor) motion picture film by several years. (mainly for speed reasons). Original Kodachrome MPic film was ASA 25 (maybe slower) pretty much limiting it to daylight or BLAZING artificial light at even silent 16 fps.
And yes still rare.--
