The Switzerland’s distinctive red flag with a white cross date back to the 14th century. Throughout its history, the Swiss flag has always had one feature that distinguishes it from all other national flags: it is square not rectangular. The Vatican is the only other sovereign state to have a square flag. The shade of red corresponds to Pantone 485C, and is a mixture of magenta and yellow. The cross is positioned in the centre of the flag, and its arms are of equal length, and are one sixth longer than they are broad.
