The resulting ethylbenzene is dehydrogenated to styrene and then polymerized to manufacture polystyrene, a common 0 is red, 120 is green, 240 is blue. Finally, to complete the spectrum of color code systems, there is HSV. The following UDF calculates the RGB values based on the degree of Hue, Saturation % and Value % of the HSV method.
