HOLD ON!!
i JUST went through the same thing and it was a nightmare. I went to Napa paint store with my color code(s) and they mixed it up and put it into a spray can(s) for me.
I did this with the wife's Subaru as well because she had a fender that needed repair. Might as well get them both done right?...
After the Bondo, after the hours of sanding, I had the Hoe primered and ready..
I cheated and bought a brand new fender for the Subaru and had primered it as well...
TIME FOR THE COLOR...
Both colors were considerably "off" in color even though I provided the color code for both vehicles. Im not talking just a little "off"...I mean by a lot! The color they had mixed for my Tahoe was lighter and had more flakes in it. I clear coated it anyway thinking this was the best I was going to get. I painted the new Subaru fender on a work table and clear coated it as well. I installed the fender and it was just as bad of contrast as my Tahoe.
Yikes!
Redo! I went to a "real" auto paint store. They informed me there was 8 DIFFERENT variations of my Tahoe's color code and 9 different variants of the Subaru's! They were able to mix me paint that actually matched! The paint may be put into rattle cans, but I assure you that it isn't cheap. At $40 a can(color) and $30 for two-part clear it adds up really fast.
Napa was kind enough to refund me for the $120 in paint they sold me after I explained the situation.
Moral of the story,..find a good paint store and test the color first.
