AMC paint codes are hidden on top of the radiator support; engine grease and oil often make them impossible to read. Typical format is BS/GBS; only the BS portion is the color code. It can also appear as QBS, PBS, TBS, etc. The first letter is the Year Code, which makes color codes confusing. BS corresponds to Deep Water Blue Pearl Clearcoat. The G in GBS is not part of the color code. Lately AMC lists codes as BS. AMC has many two tone combos on some cars and often omitted the secondary color information.
