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: WebMar 1, 2024 · According to Grassmann Color Law of additive color mixture, the mixed color could be matched by the linear combination of individual LEDs [46]. As for RGB LEDs mixed light, the chromaticity coordinates of red, green, and blue form a triangular region. The larger the triangle area is, the more color can be achieved by mixing RGB LEDs.
