Rattle can petty blue

Im pretty sure its not B5 either as thats darker than the B3. It dosnet have to be a mopar color(pretend you didnt read that) Just something thats close to a baby blueish color. I was thinking of ford blue but wanted to see if anyone has used or seen something close to the petty blue.

All I've found about it is some 999 paint code on the tags because it was a special order color or some crap like that....
