Levkowitz and Herman provide pseudocode for converting from RGB to GLHS and back. * {{cite web|ref=MacEvoy|author=MacEvoy, Bruce |date=January 2010|url=http://www.handprint.com/LS/CVS/color.html |title=Color Vision|work=handprint.com}}. Especially the sections about [http://www.handprint.com/HP/WCL/color7.html "Modern Color Models"] and [http://www.handprint.com/HP/WCL/color18a.html "Modern Color Theory"]. MacEvoy's extensive site about color science and paint mixing is one of the best resources on the web. On this page, he explains the color-making attributes, and the general goals and history of color order systems β including HSL and HSV β and their practical relevance to painters. * {{cite web|ref=Poynton |author=Poynton, Charles |year=1997|url=http://www.poynton.com/ColorFAQ.html |title=Frequently Asked Questions About Color |website=poynton.com}} This self-published frequently asked questions page, by digital video expert Charles Poynton, explains, among other things, why in his opinion these models "are useless for the specification of accurate color", and should be abandoned in favor of more psychometrically relevant models. * {{cite web|ref=Poynton2008 |author=Poynton, Charles |year=2008|url=http://poynton.com/papers/YUV_and_luminance_harmful.html |title=''YUV'' and ''luminance'' considered harmful |website=poynton.com |access-date=August 30, 2017}} * {{cite journal|ref=Smith|author=Smith, Alvy Ray |author-link=Alvy Ray Smith|date=August 1978|title=Color gamut transform pairs|journal=Computer Graphics|volume=12|issue=3|pages=12β19|doi=10.1145/965139.807361|doi-access=free}} This is the original paper describing the "hexcone" model, HSV. Smith was a researcher at [[New York Institute of Technology|NYIT]]'s Computer Graphics Lab. He describes HSV's use in an early [[raster graphics|digital painting]] program.
