White is widely worn in Brazil on New Year's Eve to symbolize peace.
During Brazil's Réveillon celebrations, many people choose white clothing for its associations with peace, renewal, and a fresh beginning. The custom is especially visible in large coastal gatherings, including Rio de Janeiro's celebration at Copacabana Beach, where crowds in white watch concerts and fireworks.
Clothing colors can also carry additional wishes in popular Brazilian traditions. Yellow may be associated with money, red with love, and green with hope or health, although meanings differ across sources, families, and regions. White remains the most broadly recognizable New Year's color.
The practice exists alongside religious and cultural customs, including offerings to Iemanjá in some communities. Wearing white is not a requirement for every Brazilian celebration, and people may combine it with other colors or personal traditions. It is best understood as a widely observed cultural symbol rather than a formal national rule.
