Abir (or abeer) is a dye common in India. It is used during the Holi festival, which is also called the festival of color, when people throw this colourful powder at each other. Abir is typically sold in markets prior to the festival.

Abir is available in synthetic or natural form. Its colors are derived from flower extracts, for instance aparajita, marigold, hibiscus and dopati. The dye is sometimes combined with mica powder to create a sparkling effect.
