1967 Dart red interior paint.. Herb’s red metallic?

The part that I see people mess up with is not realizing that in the interior it is never one color or should I say shade. Up front NO gloss color where the dash would cause glare. There always must be a certain amount of contrast due to amount of gloss or lack of.
Take a car with black interior. There are always several shades of black on seats, door panels, upper door window trim and then there is the dash and sometimes the dash pad! Several different shades O or amount of gloss vs flattener, of black!
