What might have happened is the paint shop might have used the wrong year formula to mix your paint. As an example the 1960 Neptune 703 green PPG code number is 42693 and for 1961 the code is 42698, and according to a friend of mine who paints, they are indeed two different shades. I have ran into the same confusion for my 1964 C10 in 503 Light Green. In 1962 and 63 code 503 was called Glenwood Green. This changed to 503 Light Green for 1964, 65 and 66. Code 503 in 1962, and 63 was PPG code 42977 and 1964,65 and 66 it is PPG code 43244. They are indeed different shades. I also got paint that doesn't match my original and upon investigating I got 1963 Glenwood Green instead of 1964 Light Green. Same GM color code 503 of course, but different PPG code numbers. In the late 60's 67,68 and 69 the Light Green 503 PPG code was 43523. After that it gets confusing. lol. I guess the bottom line is make sure what year paint you are actually getting, at least that is my takeaway on this.
