Flag of Scotland

The flag of Scotland consists of a white St. Andrew's cross (English saltire) on a dark blue background. A rarely used version has a light blue background. A flag not officially authorized for the population, but nevertheless frequently used, shows a red rising lion on a yellow background, surrounded by "lily double bars". This is the Scottish royal flag ("Lion Rampant").The Scottish flag is one of the oldest flags in the world, dating back to the 9th century. A tradition tells that in 832 a king Hungus (or Angus) led the Picts and Scots in a battle against the Anglo-Saxons. Hungus and his soldiers were surrounded and he prayed for deliverance. During the night, the apostle Andrew (who had been crucified on a diagonal cross) appeared and assured Hungus that his army would be victorious. At dawn, the clouds in the blue sky took the shape of a diagonal cross. The Picts and Scots were encouraged, while the Anglo-Saxons were frightened and eventually defeated. Since then, the St. Andrew's cross has been the flag of Scotland.There is no exact official definition for the shade of blue. The blue used varied over the centuries, ranging from a light sky blue to a dark navy blue. According to one joke, the choice of hue was based in each case on which shade of blue was currently available at the cheapest price. Lately, however, the Pantone 300 shade seems to have been settled on. No matter which shade is used, it must always be lighter than the one on the Union Jack. The size ratio is also not officially specified, but is generally given as 5:3 or 3:2 (with the first version being preferred). The width of the crossbars should be one fifth of the flag height.(Wikipadia)
