Ever since the first look posters of Airaa were released almost everyone in the industry got pretty shocked after watching Nayanthara’s drastic changer over for Bhavani character. Cinematographer Sudharshan Srinivasan while speaking about the movie said Most horror films use blue tones because it works well with horror and night scenes. For Airaa, we decided to break that norm and go with warm colours – reds, yellows, oranges. It was a risk we had taken and we had very few references to guide us. But now, we feel the colours have worked out very well for the film.
