The magic of colour) is a 2004 Indian Tamil-language crime thriller film written and directed by Nagulan Ponnusamy in his debut.

The film stars Srikanth, Sadha, and Kutti Radhika, while Nassar, Riyaz Khan, and Karunas play supporting roles.

Devanathan IPS, the Commissioner of Chennai Police, retires and begins a new life with his family, which includes his brother Shekar, sister-in-law Viji, and their children.

Devanathan's daughter Anitha is a 22-year-old graduate who wants to become a sincere IPS officer like her father, and his older son Ashwin is a brilliant, yet troubled and antisocial 26-year-old young engineer.

Six months after moving there, a man named Daniel arrives with a recommendation letter from a recently deceased priest in Chennai, Father Andrews, who is a schoolmate of Devanathan, to apply for a job as a tea estate manager.

The day after Shekar leaves, Daniel disguises himself as Devanathan by wearing his cap and black coat and spies on Viji when she is bathing.

She thinks it was Devanathan, and the friction between the brothers starts, which grows to an end level when Shekar leaves the house with his family.

Months later, one noon, while riding her scooter, Anitha discovers Daniel's jeep and is shocked to see him performing Hindu rituals for a woman named Abhirami.

On Devanathan's last day in service, a junior officer, ACP Prabhakaran IPS, requests him permission to perform an encounter operation on a famous rowdy called Royapuram Guna.

To save their names, Devanathan places Guna's photo inside Abhirami's work folder and fabricated her as like his lover.

At the film's end, Shakthi is seen sitting in a bus leaving Ooty reading an article on a newspaper of Devanathan's death, with Anitha revealing the truth about her father being a criminal to the entire world written in it.

Nagulan Ponnusaamy, who earlier worked as an assistant to G. M. Kumar and Raj Kapoor, made his directorial debut with this film.
