Rangoli is a traditional art of India. Rangoli is believed to bring good luck and prosperity. It is a floor art which is practiced by Indians (mostly women and girls) across the world during festivals like Diwali, Pongal etc. Bengalis call it Alpana and South Indians call it Kolam. The size and shape of rangoli designs depends totally on the person making the design. Rangoli designs can be made by sand, gulal, flowers, lime, spices etc. Where sand or gulal is used for making rangoli designs, the vibrant use of many colors is a commom thing. A special type of Rangoli called as 'Madana' is made using lime.
