- Triband (flag) (Wikipedia)
A triband is a vexillological style which consists of three stripes arranged to form a flag. These stripes may be two or three colours, and may be charged with an emblem in the middle stripe. All tricolour flags are tribands, but not all tribands are tricolour flags, which requires three unique colours.
