I hope axle doesn't mind that this thread is starting to veer off into the broader subject of paint colors. But I'll add more info if that's okay.

I just checked and I have verified "data" on 667 cars. Just GTO's.
That is 0.8% of production for 1967.
Yes, I've captured two tone (paint) cars. Not that many. Also a couple vinyl top colors other than black or white (cream, turquoise).

I spent some time crunching numbers but I'm waaay out of practice with working with spreadsheets. I think I'll have to come back

KGTO I always welcome more data.
Just quick though: Most popular color was Signet Gold, followed by Regimental Red. Some surprises: Fathom Blue and Starlight black quite rare. I included Tiger Gold which had no code but was a special color. Those were typically a "dash" or "1" on the trim tag. Chart attached. I don't know how I'd really present the data with top colors and interior colors. I need a statistician.

I may also update the thread on 67 GTO colors I started some years ago.
