Just for the record, other proprietary or industry-standard color naming systems besides Pantone/PMS that have been proposed (more or less seriously) in the past (some as early as 1997) include:

* HKS (spot, tone) <http://www.hks-farben.de/en_us/>
* RAL <http://www.ral-farben.de/content/footer-navigation/footer-anwendungen-hilfe/application-help/ral-colour-names.html>
* CI <http://colour-index.com/technical-info>
* Crayola <http://www.crayola.com/explore-colors.aspx>
* NCS (Natural Color System)
* ISCC–NBS
* CcMmYK
* RYB (red, yellow, blue), subtractive
* TSL (tint, saturation, luminance) <https://en.wikipedia.org/wiki/TSL_color_space>
