Flag of Herne Germany - Color Changing Coffee Mug

The Flag of Herne, Germany, is the official symbol representing the city of Herne, North Rhine-Westphalia. It consists of five equally sized horizontal stripes arranged in an alternating pattern of red and white, with a golden (yellow) city coat of arms centered at the hoist side. The design reflects the city's historical ties to coal mining, as red and white were the colors traditionally associated with the industry, while the coat of arms depicts Saint Barbara, the patron saint of miners. The flag was officially adopted in 1958, following the merger of several municipalities that formed the modern city of Herne.
