My Runner says its paint is 1C0 but have not found any aftermarket to match. Plastikote and Duplicolor have 1C6 but not 1C0.

Is my color OEM only?

 

Your problem is not unique, unfortunately. Toyota only carries the touchup with brush type for that. Your only choice is a custom mix from an autopaint outfit. They will have the formulation for your code. You can get it put into spray cans by the auto paitn shop (if they do that at the one you use), or you can get a vial of it and get a "preval" selfcontained compressed "air" sprayer.

I know all this because I'm in the same boat. Dark Blue Pearl from 1993 (8E3) also doesn't have a Duplicolor or Plasitkote match.

 

For a brush-in-bottle touch-up, only go Toyota. The others won't match. For a larger quantity or spray can you've got to go custom.
