General help with my 72 Corvette Stingray
craigh:
The blue body colours were different between those years.
However your Vette has likely been painted in the last 40 years so it probably won't be 100% the original colour.
What I mean by that is paints have changed a lot in 40 years with the removal of chemical and pigments that were deemed harmful. As such modern mixes are not exactly like the originals.
Also depends how close the match was when they did your last paint.
I have a set of colour cards from 1971 that were used in dealers to show customers and while they have aged with time it is clear my blue is not exactly like the card.
Have also seem many bridgehamton blue vettes here and in the US and have seen lots of variation.

It took me literally years to get the correct mix formula for my Mulsanne Blue - my Brother-in-law is a rep for PPG and in the end he had to got through the tech guys in the states. In saying that, it is 2K paint so will look very different to the original finish in terms of depth and reflectance (I did flip flop between factory acrylic finish or the 2K). So even if the formula was correct, as said in the post above the pigments are different and also it will change depending on the application and flake settlement (wet film thickness of the spray) and what sort of light it is under. Non-metallics have a much better chance at matching, but fading is an issue and as said above, who knows what actual colour it could have been resprayed.
There is a pretty good site paintref.com that lists cars, OEM codes and shows some pictures of the cars with the similar paint option in the OEM colour, this site will also filter into 'Blue Corvettes' which will list and picture every blue Corvette with OEM codes so you can seee what colours had the same codes but different names.
I have attached as an example the Mulsanne Blue list that shows how the same GM code was called different colours. Also pictures of the 1972 GM colour charts as mentioned above - don't use these to match paint! Surprisingly my Mulsanne Blue is very similar to current? Mazda Astron Blue...go figure...but the Duplicolor touch-up pen and touch-up spray was acceptably close to do some out of the way touch-ups.

Looks like 72 Targa Blue is the exact same colour as the 73 Blue according to that website paintref.com. They have the same manufacturing, Chrysler, Diztler and Dupont code.

OEM listing is the same on the colour charts, so probably. I found paint shops here in Australia struggled to convert the GM OEM codes into a mix formula (hence sourcing from PPG in the US) but maybe that was just my colour, as there seemed to be some conflicting OEM codes.
See if you can find someone locally that has recently resprayed a car the same color and has kept the formula, even better if they can put some spare paint on a flat sample coupon to compare with your car and/or park the cars together or put a painted piece of one car against the other. The base colour on a coupon will not be shiny or have the same flake lay when dry so will still look a little different...
There maybe a paint repair place / supplier that has a photospectrometer type gadget for paint matching and you can remove & use something like the gas filler cap to get a sample pot made. The local paint supplier was able to eye match a non-metallic paint for my EJ Holden and when I sprayed the bonnet and front nose panels I couldn't see any difference between bonnet and guards.

I got the touch up paint about 15 minutes ago. I applied to sme small chips that I have and the colour is extremely close if not a match. Obviously will need to dry properly but I'm pretty happy with the colour.
