A sequel titled 7G Rainbow Colony 2, also directed by Selvaraghavan and starring Ravi Krishna, is in production.

He appears distracted throughout the day and even instructs his assistant to postpone an important meeting with a big client.

He then waits for someone at Marina Beach in Chennai (Hussain Sagar which is a lake in Hyderabad in the Telugu version) with a bouquet of flowers.

Kadhir believes that his father hates him and often quarrels with him, even threatening to leave the house, only to be persuaded not to do so by his mother.

Then later at night, Kadhir overhears his father telling his mother how proud he is of their son since getting a job at such a prestigious company, which is not easy.

The only reason the father did not openly praise Kadhir is because he feared his son might misjudge him for giving him respect, only now that he is earning money for their household.

They continue arguing as they exit the hotel, which culminates in Kadhir slapping Anitha in anger, causing her to cross the road alone in tears.

Shortly after Anitha's funeral, Kadhir tries to commit suicide unsuccessfully, only to end up causing a ruckus in traffic and getting assaulted by the angry crowd, but he is saved by a group of nuns.

Back in the present day, it is revealed that Kadhir has become successful in his life but has remained mentally damaged since Anitha's death.

Selvaraghavan revealed that the inspiration for 7G Rainbow Colony came from his college days when he had been fascinated with a Punjabi girl during his education in KK Nagar.

For the lead female role, Selvaraghavan initially considered Genelia D'Souza and auditioned Mumbai model Mamta Zaveri, who was to work with Dhanush in Sibi Chakravarthy's shelved film Raghava.

The film later began production with Swathi Reddy in her first lead role, though she later opted out and was replaced by Sonia Agarwal due to her Punjabi origin.
