The Braille flag for the letter Z is orange and blue. The colours represent the number 25. However Z is the 26th letter in the alphabet. This is because the letter W was shifted to position 40, consequently Z gets a one spot upgrade to position 25 instead of its natural position of 26. By fateful coincidence, as the capital Z and N which are the same shapes at different orientations, the BRL dots coded to Z and N are in the same dot pattern coded at different orientations.
