What color pair became central to McDonald's classic Golden Arches restaurant identity?

Red and yellow became central to McDonald's classic Golden Arches restaurant identity.

The yellow arches stood out strongly against restaurant buildings, roadside signs, packaging, and advertising. Red was commonly used as the surrounding or supporting color, creating a high-contrast combination that was easy to recognize from a distance.

This palette supported McDonald's expansion during the twentieth century because it could be repeated across many physical and printed formats. The arches supplied the key symbol, while the red-and-yellow treatment reinforced visibility and consistency.

Modern McDonald's restaurants may use restrained colors, natural materials, or market-specific designs, so the classic palette is not the only current expression of the brand. It remains, however, one of the clearest visual signatures of McDonald's traditional identity.
