Light sources have similar effects on different object colors, as shown by multiple pairs of arrows in Figure 8. Similarly, it can be deduced that the chromaticity coordinates of the light source should be on the intersection of the above lines. 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.

WebThe laws of additivity and proportionality of colour matches, Grassmann’s laws, are the basis of all colour theory, but are not axiomatically true. The extent of departure of human vision from Grassmann’s laws has been periodically examined. WebGrassmann did not formally state Axiom 3 (equivalence) but used it implicitly. He stated that color matches are trivariant (first law), continuous COLOR MEASUREMENT AND COLOR THEORY I 289 (second law), and additive and subtractive (third law).
