Holi
Health impact

Another 2009 study reports that some colours produced and sold in India contain metal-based industrial dyes, causing an increase in skin problems to some people in the days following Holi. These colours are produced in India, particularly by small informal businesses, without any quality checks and are sold freely in the market. The colours are sold without labelling, and the consumer lacks information about the source of the colours, their contents, and possible toxic effects. In recent years, several non-governmental organisations have started campaigning for safe practices related to the use of colours. Some are producing and marketing ranges of safer colours derived from natural sources such as vegetables and flowers.
