As far as I'm concerned there is no mystery about the colour. I have access to a 1959 red Strat in original condition that is only a few digits after Hank's and the colour matches exactly that of my 1989 Vintage Reissue in every nuance, the two were photographed together a few years ago and they are identical. That satisfies me that Fender never forgot the colour to be able to paint more guitars the same again. I've seen many other guitars in the same colour, one owned by my colleague in our band and the other by Colin Pryce Jones - all are the USA 1980s Vintage Re-issues. The colour on the two that we own is listed as fiesta red. True there are many variants of the colour using the same name, the Japanese tend to go slightly orange by comparison and I've seen some more on the pink side, but that's in the colour mix when they perhaps overdo the yellow or white, it makes a big difference. Also, those of you who play around with photo software will understand how a colour hue can drastically change the entire tone of a picture, which is referred to in that article when mentioning different types of film.
The debate can go on and on and I'm sure that Fender enjoy people talking about it, but seeing hard evidince by way of an instrument that was very likely from the same batch that Hank's came from is pretty conclusive for me. We all know how time and exposure to light can affect a paint job but the old 1959 guitar owned by a friend of mine still has it's colour and matches our instruments thirty years younger.
