The CIE XYZ color space is fundamental to all modern color space processing. Very cool that it was defined in 1931 and has held up more-or-less unchanged to tod

  > Very cool that it was defined in 1931 and has held up more-or-less unchanged to today I wonder if the color mixing experiments have been recreated since the 30s, and if there has been any observable shifts in the curves

    There have been a bunch of additional experiments. But under well-lit conditions with typical light sources, for a typical viewer with normal color vision looking directly at an image / colored object, the 1931 functions are close enough that switching isn’t worth the transition cost.
