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

I think we may just scan his current colour.... Funny thing is when the car was painted (by my uncle at plaza Pontiac!) inside the engine, doors, truck look all like the y2, but the rest of the car is much deeper/brighter. Unfortunately he has passed away so I can't ask him about it, but my father says they didn't have enough paint to spray those areas so they only got one light coat where as the rest of the car got multiple coats plus the clear (still drip marks in the fenders!). I wish we had pictures of my fathers original 69 dart from when he was 16 years old, but that car is probably long gone!
