Luxemburg

Luxembourg is a country in western Europe that borders Belgium, Germany and France. The flag resembles the flag of the Netherlands, which has a darker blue color (cobalt blue instead of sky blue). However, the two flags do not have a common history. The fact that the Dutch king was also Grand Duke of Luxembourg in the 19th century has nothing to do with the colors of both flags. There is, however, a connection with the flag of the Belgian province of Luxembourg, since that flag is also based on the Luxembourg coat of arms.
