If you go to Mardi Gras in New Orleans, you’ll see a wide spectrum of colors, but the colors people associate with the celebration are purple, gold and green.
While there is no definitive reason how those three hues became the colors of Mardi Gras, they were chosen around 1872, and some believe they were meant to honor the Russian Duke, Alexei Alexandrovich Romanoff.
The colors are said to symbolize wealth and royalty. In 1982, the Mardi Gras King gave each color a definitive meaning — purple represents justice, green represents faith, and gold is for power.
