Period feel comes from emulsion and dyes—not modern HDR skin
`vintage-1940s-colorize` tracks mid-century viewing habits: monochrome news beside early color dyes, where lipstick and nail enamel map to specific gray steps—modern fluorescent makeup reads time-travel. Consumer negatives and Kodachrome-era materials carry warm bases or cyan masks; distinguish what audiences saw on a light box then versus your scan white point today. Uniforms, pillar boxes, and taxi schemes differ by nation—one American LUT makes European streets wrong. Neon and plastic signage spread after the war; verify architecture dates before bright tubes. Covers may push dye saturation for nostalgia; scholarship should log dye samples or reference stills and keep saturation modest. Coarse silver grain can masquerade as skin texture after color—tell grain from pores. Ration-era pigments and grimy asphalt often looked duller than retro film grades; slightly gray trumps glossy anachronism.
