Petty Blue/Coporation Blue/Basin Blue

Anyone ever do a spray out to compare these colors? I understand that there really isn't a known paint code for Petty Blue but how does it compare to Corporation Blue and Basin Blue? I think this topic has been brought u before but I'm looking for someone that has actually compared the colors.

I always assumed they were the same. 1972 was the first year Chrysler assigned the color a traditional paint code (TB3) for Super Blue (Dodge) Basin Street Blue (Plymouth) . The T indicates the year the color was first introduced . 1964 ? I am not up on my early stuff . I just know A is 1965 and so on .
