The mark consists of a 3x3 grid of nine squares. The color arrangement of the squares, starting from the top left corner, proceeds as follows: the first square is lighter blue, the second is dark blue, and the third is lighter blue. In the second row, the fourth square is dark blue, the fifth is also dark blue, and the sixth is dark blue. In the third row, the seventh square is lighter blue, the eighth is dark blue, and the ninth is lighter blue. The squares are outlined with white lines of uniform thickness, creating a clear separation and enhancing the checkerboard pattern.
