What was the name of the yellow color offered on the 1970 Buick GSX?

The yellow color offered on the 1970 Buick GSX was called Saturn Yellow. Buick paired it with Apollo White, making the GSX unusually easy to identify because the first-year model was available in only two exterior colors.

The GSX was a performance and appearance package based on Buick’s GS 455. It added bold graphics, a rear spoiler, a hood-mounted air scoop, heavy-duty suspension, and wide tires to Buick’s already powerful intermediate. Buyers could choose the standard GS 455 engine or the more potent Stage 1 version.

Saturn Yellow was not merely a generic yellow description; it was Buick’s official color name and became closely associated with the 1970 GSX. Production was limited, which makes original Saturn Yellow cars especially recognizable today. Later GSX models offered a broader color palette, so the two-color restriction is specifically a first-year detail.
