three equal horizontal bands of red (bright vermilion; top), white, and blue (cobalt); similar to the flag of Luxembourg, which uses a lighter blue and is longer; the colors were derived from those of WILLIAM I, Prince of Orange, who led the Dutch Revolt against Spanish sovereignty in the latter half of the 16th century; originally the upper band was orange, but because its dye tended to turn red over time, the red shade was eventually made the permanent color; the banner is perhaps the oldest tricolor in continuous use
