Bang on Didier.
Fender maintained a colour palette of 14 colours: These were all from the colours available at the time as used in the automotive industry. The only Pink listed by Fender up to 1964, was Shell Pink. and it was a Pale Pink. There never was a coral pink, or Flamingo pink. Leo Fender was once asked about a flame burst colour, he stated this: No such colour ever left our workshops. We had Tobacco at that time, and it was difficult to apply.
They used a mixture of Cellulose and Acrylic lacqures, depending on the application. Cellulose turnes yellow with time, in bright sunshine it can be just a few months. so a blue would look green, a white would look cream or Blonde. and a Red, which is most prone to UV light would become pink in hue.
The various Pinks or shades of Fiesta red that people refer to, are in fact reworked tobacco bodies where the yellow dye reacted with the new paint finish. Or a body painted with Cellulose lacqure affected by UV light. Those Fiesta red bodies that remained Fiesta red like 34346, had an Acrylic lacqure over the paint. It was introduced to the car industry because the Dupont colours of the time were changing colour too fast. The acrylic solved this problem.
The Guitars you saw them play Didier, are most likely reworked tobacco bodied guitars. They had large numbers of these available, and they were repainted to meet demands for certain colours. Fiesta Red was one of them. Many were repainted in europe where cellulose was the normal finish, acrylic had not been introduced in europe. Hence the colour variations.
I have all the research that was done on this, somewhere. + statements made by Leo and others, and the colour charts of the day. I will have to try and dig them out.
