The flag of the city of Quito and of the canton of Quito is defined by Article 1 of a municipal law known as Ordenanza Municipal N° 1634, passed in 1974, when Sixto Durán Ballén was mayor of Quito. According to Article 1 of that law, the flag is divided into six equally wide vertical bands, of which the inner four are red and the outer two are blue. Article 1 also recommends that the flags be 2.40 meters by 1.60 meters, which makes it a proportion of 3 by 2. The exact shades of red and blue are not specified in that law.
