Grunge Flag of Switzerland

The flag of Switzerland consists of a red flag with a white cross (a bold, equilateral cross) in the centre. It is one of only two square sovereign-state flags, the other being the flag of Vatican City. (The civil and state ensign, used by Swiss ships and boats, has the more common proportions of 2:3.)

Only the dimensions of the cross are formally established since 1889: "The coat of arms of the federation is, within a red field, an upright white cross, whose [four] arms of equal length are one and a sixth times as long as they are wide." The size of the cross in relation to the field is not formally established except on the naval ensign, for which the ratio of the size of the cross to the height is 5:8, and to the length is 5:12. A ratio of 2:3 or 7:10 to the span of the flag is usual.

Use of the white cross as a military ensign (attached to the cantonal flags in the form of strips of linen) has been used in the Old Swiss Confederacy since the 14th century, but the modern design of a white cross suspended in a square red field was introduced only during the Napoleonic period, first used in 1800 during the Hundred Days by general Niklaus Franz von Bachmann, and was introduced as official national flag in 1889.

The shade of red used in the flag is not defined by law. Swiss government bodies have used various shades throughout history.

In 2007, the Federal Chancellery published a corporate design guide for the federal administration. That guide prescribed Pantone's CMYK value of PMS 485 (both magenta and yellow at 100 percent) for use in print, and a hexadecimal RGB colour value of # FF0000 (red at 100 percent, no green or blue) for online use. However, the red colour used in the heraldry corresponds to Pantone Red 032 C, which is transposed into RGB as the hexadecimal value # F00000.

The Red Cross symbol used by the International Committee of the Red Cross, a red cross on white background, was the original protection symbol declared at the first Geneva Convention, the Convention for the Amelioration of the Condition of the Wounded in Armies in the Field of 1864. According to the ICRC the design was based on the Swiss flag by reversing of the colours of that flag, in order to honor Switzerland, where the first Geneva Convention was held, and its inventor and co-founder, the Swiss Henry Dunant.
