color code

[september2018]

My '70 B is BRG.  I'd like to match the original color, or should I say colour .

Auto paint, even a small 'touch-up' amount is rather expensive so I'd like to avoid, if possible, a trial and error process.

From what I've learned, color GN29 is shown as Dark BRG used from 1963-70. There is a BLVC25 BRG shown for '70-71.  Is there a way to determine which my vehicle had originally?  Is the color code located anywhere on the vehicle?

Thanks

I think I know the chart you're referencing and it was compiled by some from collected data. Nice job and a lot of detail, but it's not a factory list. 

BMH color charts show the BLVC25 code BRG only for '70-72 and the GN25 code BRG code 63 through only '69. No overlap, though with 'rationalization', BL may have used some leftover paint for some early 70 cars.  The BMH charts have been pretty accurate thus far.

BL often used supplies on-hand from the prior year into the next model year (rationalization, just mentioned, usually for distributors, carbs, etc., making 'break' points of what started/ended when more muddled) and would sometimes retitled leftover, unshipped cars to the next model year.  I've not heard any instance of paint used that way, but I'd want the year-correct color for my car.  Also, the '70 B was a major departure from prior years, having many different features, mechanically and appearance-wise, from the earlier cars, including being unique in it's 1-year-only split rear bumper and a recessed grille that was only used for the 1970-72 model years.  So if your car has these, chances are it's not an earlier car retitled and the BLVC25 code is probably correct.

Most body shops, especially restoration specialist, have spectrophotometers, a fancy way to say color analyzers.  We use them in the garment industry and they are very accurate, if maintained.  A shop should be able to polish-up a section of old paint and read it to get close enough to determine which code is closer to use.

Hope that helps you.
