In Taekwondo, practitioners wear colored belts to signify their rank and progress in the martial art. The belt system typically starts with a white belt for beginners and progresses through various colors, such as yellow, green, blue, and red, before reaching the black belt, which represents advanced skill and knowledge. Each color belt indicates a specific level of expertise and understanding of Taekwondo techniques, forms, and sparring. The journey through the belt ranks often involves testing, where students demonstrate their skills to earn promotions to higher belts, reflecting their dedication and growth in the discipline.
