Reappraisal of colour matching and Grassmann

Grassmann's laws describe empirical results about how the perception of mixtures of colored lights (i.e., lights that co-stimulate the same area on the retina) composed of different spectral power distributions can be algebraically related to one another in a color matching context.

"Grassmann's law, named after its discoverer Hermann Grassmann, is a dissimilatory phonological process in Ancient Greek and Sanskrit which states that if an aspirated consonant is followed by another aspirated consonant in the next syllable, the first one loses the aspiration. The descriptive version was given for Sanskrit by Pāṇini. Here are some examples in Greek of the effects of Grassmann's law: " - Grassmann color law

WebGrassmann introduced an extensive formation as the totality of elements obtained by variation of the generating element [HGW11, 28].
