There are a lot of shades of Fiesta Red. It became very popular in the UK because of The Shadows. Hank Marvin had a Fiesta Red Strat and Jet Harris had a sunburst P Bass - the first in the UK. Later all The Shadows sported Fiesta Red guitars, and they were so popular that the UK distributer started respraying UK basses Fiesta Red, usually over Sunburst as Fiesta Red was a custom colour and thus more expensive. This accounts for the variation in shade for UK 60's basses.
My 62 is a factory finish not resprayed.
