Power Brake Booster Color
Short answer: The booster was cadmium plated — a silver with a slight gold hue (“yellow cad”), not as yellow as some other GM boosters (Jim Mattison discusses the correct color in the magazine articles on his 1967). The spray-can “cadmium” paints are only a look, take 5–6 cans and several steps, and don’t match real plating.
Better to have it replated — shops advertise in Hemmings, or use a local plating house (yellow cad varies in hue by plater/part). Plating outlasts paint. One named rebuilder: Steve Gregori redoes them in the correct hue with all-new rubber for ~$120 (brakeboosters.com).
