In 1966, Connie Chan Po-chu and Josephine Siao Fong-fong starred in multiple contemporary films, cementing their onscreen persona as virtuous young women while becoming the hottest youth idols of their time. Colourful Youth remains the only contemporary film to feature both of them. Filmed in Eastmancolor, the song-and-dance spectacle keeps its fingers on the pulse of its era and presents the vigour of the modern times.
In search for her perfect groom, Sit (Tang Bik-wan) goes to a bordello and falls in love with talented Lee (Mak Bing-wing). Burning with jealousy, the Imperial Tutor's son (Siu Chung-kwan) frames Lee for treason, yet accidentally gets killed by Sit when she rescues Lee. To avenge his son's death, the Imperial Tutor tricks the couple into joining force in overthrowing the emperor and plans to accuse them of treason. Sit, who turns out to be the emperor's long-lost daughter, follows Lee to the palace for investigation. In the film, Tang Bik-wan put on various guises in her character, e.g. dressing as an ugly and Zhongshan dialect-speaking woman when she weds, disguising as a man while investigating. She proved herself a well-rounded diva with her marvellous singing, switching between different dialects and operatic styles. The scenes with Mak Bing-wing also show great chemistry, as the duo evolve from quarrelsome lovers to husband and wife.
