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). WebThe optimized peak wavelengths of the five monochromatic LEDs are 385, 467, 524, 564, and 632 nm. The blue light hazard efficiency of radiation (BLHER) of the practical mixed white light is always less than 0.06 when its correlated color temperature (CCT) changes from 2500 to 7000 K.

WebIf x, y, and z are distinct stimulus colours, and if the symbol = indicates visual matching, then the laws state that: (a) If x = y, then x + z = y + z (if equivalent colours are added to equivalent colours, then the sums are also equivalent); (b) If x = y, then x − z = y − z (if equivalent colours are subtracted from equivalent colours, then the …
