1969 dart ready for paint....yellow looks wrong?

True, but I always felt when we painted the car 25 years ago it was wrong. Now that I see the y2 colour I'm torn between what he currently has and going original. Y2 seems so dull

Show him some Y5 color cards next to the D2 cards and he’ll see what a fuller nicer color yellow the Y5 is and will look beautiful on his car.
