what color to paint 67 barracuda notchback

At the end of the day you'll go with what you like I'm sure.
My opinions ?, I dont like gray, especially on a car with no side marker lamps.
Its a disappearing act in some conditions. Gray car in a gray road on a gray day.
Orange and black scream haloween at me.
If I had the opertunity to delete the vynil top, I would in most cases.
The only vynil top I would keep correct is a mod top and that would have to be the yellow modtop scheme.
