Red and yellow became the color combination most associated with McDonald’s restaurant branding after the Golden Arches emerged.
Yellow connects directly to the company’s arches, which were designed to stand out clearly against the roadside environment. Red became a strong supporting color in signs, buildings, packaging, uniforms, and advertising. Together, the colors created a high-visibility identity that could be recognized quickly by motorists and customers.
The palette also reflects the visual conventions of fast-food signage, where bold, contrasting colors help a restaurant attract attention. McDonald’s later introduced more restrained architectural and environmental designs in some markets, but red and yellow remained strongly tied to the core identity.
The colors should not be confused with the shape of the logo itself. The Golden Arches are the symbol; red and yellow are the best-known supporting brand colors.
