The narrative of the film explores the ups and downs in the life of a single, working mother Chandrima Mukherjee (played by Rituparna Sengupta), and the relationship with her daughter, Esha. After her husband (played by Priyanshu Chatterjee) Dibakar's tragic demise, Esha and Chandrima had none but each other. However, being the strong and independent woman that she has always been, Chandrima raised her daughter all by herself. Never did she let the absence of a 'male parent' affect their bonding, or so does she think. Time flies by and, as Esha grows into adulthood, distance starts to grow between the duo. It is only after a pregnant Esha's suicide-attempt that Chandrima realizes how little she knows about her daughter's life outside the house. Especially since college days, Esha got carried away in the newfound freedom. Whereas, Chandrima busy in her professional life, has failed to keep track of this change. Eventually, they had become, as Chandrima comes to admit, strangers under the same roof. Thereafter, Chandrima starts to introspect Esha's perspective and, in the process, discovers a side of her daughter she never knew. What follows is how she, with all the strength of her love, brings Esha back to a normal life. Esha too, comes to realize that Chandrima was always her closest friend; had been there for her and always will be. Through this heartwarming story, Colours of life reflects on our lives in the contemporary world where we, always engaged in mechanical communication, are perhaps.
