Kawasaki paint codes yes, as referenced by the Kaw part numbers on the LH column of your attachment.
Kawasaki paint codes that any supplier can whip up, not that I am aware off.
Are these numbers supported anymore, I don't think so.
The closest paint supplier that matches these old 70's and 80's colors are per the previous links in other threads related to this question.
www.colorrite.com/ These guys only go back to 1986 for some models only.
www.cyclecolor.com/ Cycle color caters more to our year of bikes and have been around for a long time.
I Hope this lends some clarification to this topic.
