Mardi Gras Beads or throws are a fun part of the Carnival festivities in New Orleans, Louisiana.
Like all of the great traditions of Mardi Gras you can find right here at Holiday Party SOS, the beads have a rich history. The true meaning of Mardi Gras beads starts with the colors. The origin of Mardi Gras beads and their meanings was determined by Rex, the King of the first daytime Carnival in 1872. Rex was really Russia's Grand Duke Alexis Romanoff. Being of royalty, he determined that he would use the royal colors for this celebration: purple for justice, green for faith, and gold for power.
