Across north India, the brief season of spring weather erupts with the festival of Holi—a no-holds-barred celebration in the villages and city streets. Water-sprays everywhere, children throw coloured powder at each other, and soggy T-shirts and kurtas abound. It’s a holiday some girls experience as an equalising moment, a rare chance to play freely with boys. Other girls, though, view Holi warily—as a celebration that gives cover to sexual harassers. It’s a charged moment in the gender politics of Indian life, and in many communities the soundtrack to that experience is Rang barse, as performed by the Bollywood legend Amitabh Bachchan in a film from the 1980s.
