What paint codes are these?

[Skunksmash]

This is a pic of my old 82 chevy silverado. I would like to know the paint codes for the blue, and the silver/grey/silvery grey that came on the truck. I was hoping that someone here was already familiar with this paint scheme and remembered the codes. I tried looking them up myself, but for some reason there just isn't any way to tell because they have too many colors that year that are too close together. They have several silvers and greys and greyish silvers. I'm thinking that the blue is the only dark blue they had that year, but I can't be sure.
