Mix two teaspoons of Turmeric powder (haldi) with double the quantity of gram flour (besan). Turmeric and gram flour have magical qualities that are very good for the skin. Ordinary flour (atta), refined wheat flour (maida), rice flour, ground nut (arra rot) powder, fuller`s earth (multani mitti) and even talcum powder can be used as substitutes for gram flour.
Other methods:Flowers like Cassia fistula (Amaltas), Marigold (Gainda), Yellow Chrysanthemums and Black Babul yield different shades of yellow. Dry the petals of these flowers in the shade and crush them to obtain a fine powder. Mix an appropriate quantity of the powder with besan or its substitutes and see your festival come alive sans any harmful effects of chemically-loaded colours.
