Abhimanyu was walking. As he walked, he thought about Krishnakoli. How strangely the girl had changed. Now she is a busy heroine of Bengali cinema. Abhimanyu could still see his friend Jayantar's new wife when he opened his eyes. Krishnakoli's entry into cinema was completely unexpected. Director Subirdar was Abhimanyu's first assistant at the time. Suddenly, a co-star was bedridden in an accident, so Abhimanyu made the offer to Krishnakoli on Jayantar's advice. Although there was some hesitation at first, Krishnakoli finally agreed. Much to Jayantar's enthusiasm. Then it was history. The emergence of a new star in the Bengali film industry. Despite the disapproval of her in-laws, Krishnakoli signed one film after another. After that, it didn't take long for the fire to burn. After the scandal with actor Ranbir Sen, Krishnakoli herself left home. Leaving her son, leaving her husband. Such life stories in the film industry are not new, they happen often. Yet Abhimanu wonders, why did Krishnakoli become like this? And has Krishnakoli herself become happy? A deep pain covers her. Krishnakoli only feels that she is of no use to anyone. Standing in front of the light with paints, acting as someone else's role, and constantly moving towards an uncertain future. What is the point of dragging this directionless lifeboat? 'Colorful World' is the story of a life questioned by change, transition, and pain.
