Deepika Padukone is all set to darken her skintone for Rajinikanth's Kochadaiyaan. The actor's complexion is reportedly few shades lighter than the south superstar, reports Subhash K Jha for Mumbai Mirror.Reportedly, this decision was taken to increase their on-screen compatibility in the movie."We're applying a special imported technique to the film wherein the actors' looks, including their skin-tone, has to be compatible. In Kochadaiyyan, the demands of digitalised filmmaking are different. Deepika's complexion is many shades lighter than Rajiniji's. When we suggested that her skin colour should be suitably modified on screen, Deepika sportingly agreed," a source told Mumbai Mirror."On Tuesday, Deepika flew to Chennai for the 'looks' test. In a marathon session, after comparing her skin-tone to Rajinikanth's, it will be digitally darkened to match his," read the Mumbai Mirror report."The demands and dynamics of the technique known as 'performance-capturing' that we're using for the first time in Indian cinema are different. It requires many adjustments and modulation in the actors' on-screen performance and personality. Deepika has an important role. She is completely in-sync with the unique technique and willing to do whatever is required," co-producer Dr Murli Manohar told the tabloid.
