Datsun paint codes with color samples...
Whew, hard to read those codes, but I was able to add a bunch of unknowns to my database for future use.
I updated my chart... but not really happy with not actually knowing which colors apply to which years. I hate to add information that isn't verifiable, but in this case I guess any information is better than no information. Hopefully over time we can refine this.
Thanks for your help!
