Artificial or synthetic colours are chemicals that are commonly synthesized from petroleum and are mass produced. The final products undergo rigorous testing to ensure that they contain no traces of petroleum. According to the FSSAI regulations, food manufacturers can use artificial colours.

Also, artificial food colours need to be used in foodstuffs according to the permissible limit set by the food regulatory authority. Moreover, it is mandatory to mention colour on food labels but this becomes difficult on Indian sweets and savouries when they are sold open and not as packaged foods.
