PlanetInverts has a grading chart.
http://www.planetinverts.com/crystal...g%20guide.html
There are 2 specific grading options in that page. And yes, they are just a different color.

There is also the German grading system.

As for the PRL grading, it seems each PRL breeder has their own idea of what an SS or SSS or S colored shrimp is.

Cull or sepparate any shrimp of a lower grade, if possible pair up your highest grade males and females so that they will have more high grade babies.

PFR are a pain to grade, personally I shine a flashlight on them and set out any that seem more transparent, I can't tell much of a difference between PFR and lower grade juvies doing anything else, but I'm sure someone has another possibly better method
