Europe
Underground roundel red, royal navy, and pub-tile green — the codified colors of the British capital.
London is one of the few cities whose palette is partly enforced by transport authority. Underground red (the roundel red, technically Pantone 485), Underground blue, Buckingham red, royal navy and Cambridge blue all appear on official documents. The vernacular layer adds Victorian garden brick (#9F4A3C), London Plane tree green, and the deep enamelled green of pub tile dadoes — all present across Hampstead, Bloomsbury, Marylebone, and the City. Even the typeface (Edward Johnston's, 1916) is owned by Transport for London.
