In which dynasty did the emperor's yellow robe begin?

The robes of ancient emperors. "Yellow robe" is often regarded as a symbol of the color of ancient imperial costumes. The "yellow robe" originated in the Tang Dynasty, and was a special costume for emperors. Yellow clothing has always been popular in ancient China. After the Tang Dynasty, the emperor was unwilling to wear yellow robes with ordinary people. When Tang Gaozu was in office, he "forbidden ordinary people to wear red and yellow clothes". Tang Gaozong reiterated that "nothing is allowed to be yellow". But at this time, the regulations are not strict, and it is common for ordinary people to wear yellow clothes. In the Northern Song Dynasty, the Northern Han Dynasty and the Qidan invaded the south, and Zhao Kuangyin led his troops to the north. In 960, when he arrived in Chen Qiaoyi, all the officers and men were crowned emperor in yellow robes, and returned to Bianjing to officially ascend the throne, thus making the yellow robe a symbol of imperial power. Song Renzong also stipulates that ordinary people are not allowed to wear yellow robes or make patterns. Since then, not only the yellow robe is unique to the emperor, but also the yellow robe is unique to the emperor.
