I just repainted my K5. The color code for the side is 46U/WA9228L (called blue granite metallic in '06 and Stealth Gray in '07) and the dark blue is GM58/WA919L called Dark Steel Blue. I don't know what year or vehicle the dark blue is from and if anyone can tell me it'd be greatly appreciated. I just picked it from some GM color samples. I need to know what year and model vehicle the Dark Steel Blue was offered on.
