Centuries after naturalists used it to define the colors they saw in the natural world, Werner’s Nomenclature of Colours is back.
"The nomenclature of colors we use today is really a machine language–numerical hex codes crafted to communicate with software on computers and printers.

Though many have fallen into obscurity, at least one is now accessible to anyone with access to the internet: Werner’s Nomenclature of Colours."
