Vietnamese five-color flags
In Vietnamese culture, five-color flags or five elements flags are traditionally flown during festivals and religious ceremonies. A five-color flag consists of five concentric squares in red, green, yellow, and blue, representing the five elements. The order of colors varies. The outermost square has three ragged edges, similar to fringing. The center of the flag is sometimes defaced to commemorate a specific concept or personality.
Historically, some imperial and military ensigns followed a similar pattern.Variations
