Name and register this color

The Official Color Registry (OCR) is an independent, privately run registry. It is not a government agency or an international standards body, and registering a color name does not give you a trademark or ownership of the color itself.

Reference names

Names this exact code carries in public color lists. They are reference data, not registrations, and the code is still free to register under a name of your own.
