About the Flag of New Jersey

Flag of New Jersey

1. Design and Symbolism
The flag of New Jersey uses classical imagery to represent state characteristics. It consists of the coat of arms of New Jersey on a buff background.  
The central blue shield features the image of three plows in a column to represent the state’s agricultural roots. One of New Jersey’s nicknames is “Garden State.”
Above it is the helmet of a knight facing forward and the head of a horse facing left. Between them are twisted blue flowers. The arrangement implies self-governance for the state. 
On the sides of the shield are two Roman goddesses. On the left is Liberty, holding a staff with a Phrygian cap on top to symbolize freedom. On the right is Ceres, carrying a cornucopia with overflowing fruits to signify abundance.
At the bottom, you will see a flowing blue ribbon with red borders. It contains the state motto, “Liberty and Prosperity.” It also includes the year in which New Jersey achieved statehood, 1776. 
2. Adoption
New Jersey adopted this design for the state flag on May 11, 1896, and modified it slightly in 1928. 
3. Technical Details
State law defines the Jersey blue parts of the flag as Cable No. 70087. Meanwhile, the buff field is Cable No. 65015. Their hexadecimal color equivalents are 2484C6 and E1B584. 
The goddesses are wearing sandals with their feet peeking out at the bottom. Liberty is directly stepping on the section of the ribbon bearing her name. Meanwhile, Ceres is right above the word “Prosperity.” 
4. History
In 1777, Pierre Eugene du Simitiere designed the coat of arms of New Jersey with the plows and goddesses. He is a Genevan American portrait painter and naturalist. He served as an artistic consultant for the committees involved in the design of the US seal. 
In 1896, the New Jersey General Assembly approved the flag as a state emblem. They placed the coat of arms on a buff field. 
In 2016, NJ.com and NJ Advance Media ran an unofficial design contest for a new state emblem. The goal was to find a simple yet recognizable flag. Andrew Maris won with a tricolor creation inspired by the Revolutionary War uniform of the Jersey Blues.
The militia wore a red waistcoat, a blue coat, and a white sash. Meanwhile, the flag has a red top and a blue bottom separated by a white diagonal band. A lone white star represents New Jersey as the first state to ratify the Bill of Rights. 
5. Flag Facts
In 1779, General George Washington ordered that the uniform coats of the New Jersey Continental Line army regiments should be dark blue with buff facings. Before this directive, only Continental generals and their aides wore buff facings. These revolutionary colors are the inspiration for the flag’s hues. 
The New Jersey flag is the only state flag in the US with a buff background, although most displays use yellow due to unfamiliarity with the color. 
6. Flag Usage
The state flag should fly at the Capitol whenever the parliament is in session. All government buildings and schools must have one, keeping it atop the pole from sunrise to sunset. 
According to a law passed in 1938, everyone has the right to display the flag. Citizens can hoist it on their homes or vehicles. They can use it to identify themselves as New Jersey residents outside the state.
