With a red car in particular Gary's suggestion is by far the best; all the colours are affected by sunlight to some extent, but red, just like with red painted cars, does seem to age and weather the most.
You can buy small pots of gel coat from Westfield (about a tenner) for making repairs. But even though it's the same colour, the match can vary from spot on to miles out depending on how much the car has faded over the years.
You would have the same issue if you tried to match paint to the original colour; it might match that, but stand out like a sore thumb on the car!
Oh, and to answer the original question; no, we don't have colour charts or lists, the factory has used a variety of suppliers over the years. I presume as a batch of one colour started to run out, it would be replaced by which ever supplier offered the best price. There isn't therefore a definitive 1998 supplier or 2009 supplier in the same way that there would be consistency on a model years paint finishes with a tin top supplier. (Hence the batch codes inside the grp panels, so that at least they can be matched at the time of manufacture, (it also used to identify which mould set a set of bodywork had come from. Not sure how many moulds they actually have since it went out-of-house).
