For those looking − as the GP said, it's not fantastically organized − pigments information is available here: https://www.handprint.com/HP/WCL/waterfs.html. Top links yield access to pigments, organized by "color family".

Two other similar resources on pigments − always good to check what's in the tube before buying!
