Basically it is impossible to say what colour that is on your bike, it differs between paint brands and mixture. You need to do a research on who painted that and what brand paint he used and colour he mixed. Then there might be a change in the colour with age so the mixture receipt might be tweaked a bit to get exact shade. A good painter that works with the same brand paint might mix the right colour for you if he gets the basic information. You won't get any help at all with the Indian original colour charts or receipt.
