The flag of Primorsky Krai is a rectangular panel, divided diagonally by a white stripe and consisting of two triangles: the top one, placed at the flagpole, red and the bottom blue. In the upper corner near the shaft there is a golden image of a Ussuri tiger walking. The ratio of the width of the flag to its length is 2:3. The width of the white stripe on the shaft shall be one fifth of the entire width of the flag; the height of the tiger figure should be one fourth of the width of the flag on the pole. It is a representative, identification and legal mark, drawn up and used in accordance with the rules of vexillology. The idea of the flag was proposed by V. A. Obertas, a professor at the Institute of Architecture, FESTU.
