GM code WA818T - blue
This blue automotive paint color is most commonly known as Steel Blue. Other common color promotional names include Sonic Blue, Twilight Blue, and Supersonic Blue. The color formulation has been used between 2011 and 2013, primarily by Chevrolet; but also by GMC, GM, and Buick. We have records of this color appearing on the following models: Chevrolet, Chevy Truck, Corvette, GMC, Equinox, Terrain, Trax, Malibu, Enclave, Aveo, and Buick. See the full detailed list below.

GM paint manufacturing codes come in two forms, the short 1 to 3 digit model/year code which changes frequently; and beginning in the 1960's a longer 4 digit code which starts with the letters "WA" or "WE". Sometimes called "Fisher Paint codes"; codes beginning with WA are production paints, WE are commercial or special order paints with codes typically starting with '5' (i.e. WE5xxx). Starting in 1994, GM began using a letter as the last digit for all new WA paint codes.

Variations of the exterior paint code WA818T, which may appear on body data tags include: 818T, U818T, and L818T (the prefix U for upper body, or L for lower body). Location of the GM paint code plate varies depending on the year and model of the vehicle common places are on the top or near the top of the back engine compartment shroud panel just behind the steering wheel, hinge pillar of the driver's side door, trunk or rear hatch, side of door, glove compartment, or behind the driver's seat. Check for either the short year/make/model paint code or the longer manufacturing (Fisher) paint code.
