White is the traditional color worn by many people during Brazil's New Year's Eve celebrations, especially at Copacabana Beach in Rio de Janeiro.
The custom is associated with peace and renewal, and it is often linked to Afro-Brazilian religious traditions in which white clothing has ceremonial importance. Visitors may wear entirely white outfits or combine white garments with colors believed to represent wishes such as love, prosperity, or health.
Rio's Réveillon celebration is famous for its huge beach gathering, musical performances, fireworks, and offerings associated with Iemanjá, the sea deity honored in Candomblé and Umbanda traditions. These elements coexist with secular parties and public concerts.
White clothing is a widespread custom rather than a legal requirement or universal rule. Some celebrants choose additional colors for symbolic reasons, but the defining visual tradition of the Copacabana event is the large sea of white clothing.
