What is the difference between Sindoor and Kumkum

Kumkum is a red-coloured powder, identical to Sindoor, but is different in use and symbolism. Unlike sindoor, kumkum is used in rituals, prayers, and religious ceremonies, and can be used by married and unmarried women. Kumkum is made with a mix of turmeric, saffron, and lime, and has a bright red shade that makes it pop out. Kumkum is generally used to apply Tilak to self or others, and even to deities, idols, images of Gods, and the like. In some parts of India, Kumkum powder is also watered down and then applied on the hands and feet as aalta.
