White? Cream? Help!

What exactly are you wanting to do? Get some spray dye and dye it back? Connect the dots for us. If that's what you want, this is really simple. Take it to a paint store and let them come out with their color match gun, shoot the seats and they can mix up the perfect shade. But of course, since you didn't tell us what the end result is you're doing, we can only guess.
My 72 Scamp kind of looks cool with the Tawny and vertical seam, cream color scheme but I have a 75 scamp with re upholstered rear seats (black) and a 71 valiant (blue) for parts and other Mopar parts I have acquired over the years. (like that console)
I could go black and get new black buckets (way easier) . I would have to paint all the cream accent trim black inside as well.
