So the paint codes are all listed in the end of the parts books. Just like 250g60 posted. Now if you have access to an old Datsun/Nissan paint chip book you can reference the Patrol paint codes and numbers in these books. While the parts books just say 562 "blue", 558 "green" ect ect with the paint chip book you get the actual real names of the colors such as "dragon green" using the codes listed in the parts books. The only real problem is these codes are somewhat lost in time, meaning a paint shop can get or may have the info but they can't just order up the color anymore. So it needs to be reproduced and mixed in house by the paint supply shop. Which they can do.
I have the Nissan paint chip book that paint shops use. I will see if I can scan the pages in it with the Patrol colors and get these uploaded.
Cheers
