> Consequently, we need to adapt how we model color differences, as the current standard, ΔE, recognized by the International Commission for Weights and Measures, does not account for diminishing returns in color difference perception. This isn't to reduce the notability of the article, but isn't BIPM's interest in any color-perception stuff basically limited to making lightbulbs roughly equally bright? (i.e. https://en.wikipedia.org/wiki/Luminous_efficiency_function https://en.wikipedia.org/wiki/Luminous_efficiency_function) I guess I don't see how even nonlinearity in perceptual space matters for that purpose.
