WebGrassmann’s Law (=GL) is generally regarded as a quintessential example of regular sound change, though dissimilation processes are generally said to be quite rare and sporadic. 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. Discovered by Hermann Grassmann these "laws" are actually principles used to predict color match responses to a good approximation under photopic and mesopic vision.
