You don't need to match the LEDs to the eye, matrix math will take care of that. Besides the color response of the S, M and L cones (in trichromatics) overlaps, and are composed of quite complicated curves. Using the CIE diagram, you can reproduce any color inside of a triangle defined by a set of primary colors as the vertices, with any other set of primaries given the color to reproduce lies within both triangles.It is a known there is a sex-linked gene that gives some percentage of women 4 sets of cones. Hense the belief that women are better at color than men. On average, it's true!
Please, allow me to insist: who's going to accept the result (of the sky remembrance, I mean)?
