Key points
True 1980s fluorescent neons (hot magenta, electric cyan, acid yellow) exceed the sRGB gamut — modern screens approximate them but cannot fully reproduce the physical day-glo effect.
Miami Vice pastels are medium saturation (40–60%), medium-high lightness — distinctly not fluorescent, achieving luminosity through contrast with dark backgrounds rather than intrinsic brightness.
Memphis Design used primary and secondary colors at full saturation but conventional lightness — the impact came from pattern conflict, not extreme chroma.
Retrowave and synthwave palettes are contemporary digital interpretations — they push saturation and add gradients and glow effects that didn't exist in original 1980s materials.
