The 1835 Sretenje Constitution described the colours of the Serbian flag as bright red, white and čelikasto-ugasita (that could be translated as steelish-dark). The constitution was criticized, especially by Russia, and the flag was specifically singled out as being similar to the revolutionary flag of France. Soon afterwards, Miloš Obrenović was requesting to the Porte that the new constitution should contain an article about the flag and coat of arms, and subsequent ferman (1835) allowed Serbs to use their own maritime flag, which will have "upper part of red, middle of blue, and lower of white", which is the first appearance of the colours that are used today.
Serbia used the red, blue and white tricolour continuously from 1835 until 1918 when Serbia joined the Kingdom of Serbs, Croats and Slovenes, later known as Yugoslavia.
After World War II, Yugoslavia was reformed into a socialist federal republic, composed of six republics, one of which was Serbia. Each republic was entitled to its own flag on the condition that it contained the socialist red star. Following the breakup of Yugoslavia, Serbia initially continued using the same flag; the 1990 Constitution of Serbia stated that flag and coat of arms of Serbia can only be changed by the same procedure used to change the constitution itself, which required absolute majority of voters to support it. 1992 Serbian constitutional referendum asked the voters to choose between the flag with and without the star, with red star gaining the majority of votes, however not the absolute majority of voters. The red star was nonetheless removed from the flag in 1992 by a recommendation by the Serbian parliament; however, the coat of arms remained unchanged. In 2003, however, the government of Serbia issued a recommendation on flag and coat of arms use, that preferred using different symbols from the ones in the constitution. The 2006 Constitution of Serbia stated that state emblems would be regulated by law; the recommendation remained in use until 11 May 2009, when the actual flag law was enacted. On November 11, 2010, a visual redesign of the coat of arms was enacted, which is currently used on the state flag. 
The Pan-Slav colors (red, blue and white) represent freedom and revolutionary ideals.
the principal field of the coat of arms represents the Serbian state and displays a white two-headed eagle on a red shield; a smaller red shield on the eagle represents the Serbian nation, and is divided into four quarters by a white cross; interpretations vary as to the meaning and origin of the white, curved symbols resembling firesteels or Cyrillic "C's" in each quarter; a royal crown surmounts the coat of arms.
