Still got to love the Ferrari red originals! Maybe red with a big gold badge with the Ferrari leaping stallion, or with white oval number plate? With that body style it will hard to go too wrong with any color scheme you have mentioned! Just no purple/pink!
For some inspiration here is a shell commercial /youtube link of classic f1 racing cars.
