When we say "same (S,M,L) response" are we normalizing that 3-tuple? E.g. are spectra integrating to (1,1,1) and (2,2,2) metamers?
I guess the color of (1,1,1) and (2,2,2) is the same, but they have differences in brightness or other aspects
@ak-47. Actually no. They would project to the same chromaticity in the intensity normalized 2D chromaticity diagram, but they definitely trigger a different cone response.
Think of metamers as indistinguishable to the brain when observed.
Oh, I see, thanks Kayvon!
