What's the difference between alpine 1 and alpine 2?

[2mAn]

Just like the title says....

I'm getting my bumpers painted and need a paint code, but not sure which one to go with.

So what's the difference and what it's the paint code?

Thank you in advance

Alpine 1 code:146
Alpine 2 code: 218

Alpine 2 is "whiter" and less yellow than alpine 1
