Rainbow is a 2008 Indian Telugu-language romantic drama film directed by V. N. Aditya and starring Rahul, Sonal Chauhan, and Sindhu Menon.

As Shyam helps Swapna navigate her challenges and pursue her dream of becoming a painter, they develop a deep bond.

However, complications arise when Swapna regains her sight through a surgery, and Shyam fears losing the special connection they share.

The narrative explores the emotional journey of the characters, highlighting the significance of inner beauty, unconditional love, and the power of dreams.

[12] Y. Sunitha Chowdhury of The Hindu opined that "One doesn't understand why the director had to show the hero as being colour blind just to elevate his character and the heroine undergoing a change of heart just because she realises Shyam is suffering from an ailment looks unrealistic".
