Yellow clothing is traditionally worn for luck during Colombia's New Year's Eve celebrations.
In Colombia, yellow is popularly associated with prosperity, happiness, optimism, and good fortune. Some people wear yellow underwear, while others choose yellow clothing or accessories for the midnight celebration. The practice is part of a wider Latin American tradition in which particular colors are believed to attract specific hopes for the coming year.
Customs vary by family and region, and color symbolism is cultural rather than scientifically proven. Yellow is not Colombia's only New Year tradition: families may also gather for a midnight meal, make resolutions, or observe other local customs. Similar yellow-clothing traditions can be found in parts of neighboring South America, so the practice should not be treated as exclusive to Colombia. The key distinction is that yellow is linked with luck and prosperity, while other colors may carry different meanings in other countries.
