The Buick Trishield is rooted in the ancestral coat of arms of the automaker's founder, David Dunbar Buick. That crest was a red shield with a checkered silver and azure diagonal line from the upper left to lower right, a stag above, and a punctured cross below. The division adopted this on its radiator grilles in 1937. In 1960, the logo underwent a major overhaul. Its single shield was replaced by a trio in red, white, and blue—denoting the [[Buick Lesabre|LeSabre]], [[Buick Invicta|Invicta]], and [[Buick Electra|Electra]] then in the Buick lineup. It was supplanted by the Buick Hawk in the 1970s, but reemerged in simplified form in the 1980s. The Trishield became monochromatic in 2005, but the traditional colors returned in 2023.
