PS Blue Bottle is their Arctic Express. It is just a straight anti-gel, with no cetane or detergents added. It is an economy anti-gel, whereas the white bottle has basically the whole package. Then the silver bottle, called Diesel Kleen, is a summer package with no anti-gel but more cetane and detergents.
But even the blue bottle is not a degel or deicer. It is just an anti-gel. The red bottle 911 is needed to fix an already gelled fuel to reintegrate the paraffin.
