Paint code is different WTF?????

[66/87chevy]

So today I started looking into getting some touch up paint for a few scratches on my 87v20.

The paint code in the glove box reads WA-L5118
So I go down to the local auto parts and start looing for the correct paint code to match my RED paint. Well it looks like I'd been had once again WA-L5118 is NOT RED it is BLACK. WOW !!!! I bought this truck last winter from a guy in Minnasota that told me alot of BS and I fell for it. But on the positive side I do love the red paint. Even though it's NOT the original color like the guy said it was. I don't see any signs of any black on this truck at all.
