Saturn used many different locations for the paint color plate over the years, making it hard to find. The paint code is usually in the glove box or the spare tire well; if not there, it may be elsewhere. GM did not standardize the location across makes and models. Codes like 51/WA316N are often preceded by BC/CC; two tone cars may show U or L (Upper/Lower), e.g., BC/CC U316N or BC/CC L316N. There can be eighteen different code 51's so 316N identifies the color.
