The flag of Tamil Eelam was designated as the national flag of the aspirational state in 1990. The tiger symbol of the Liberation Tigers of Tamil Eelam (LTTE) was created in 1977, differentiating it from the LTTE's emblem by leaving out the letters inscribing the movement's name. In 2005, the LTTE released a guide providing instructions and explaining the correct usage of the Tamil Eelam Flag. The guide written in Tamil specifies the regulations for flying alone or with national flags of other countries, and for general handling of the flag. The flag has four colours: yellow, red, black, and white. It is banned in Sri Lanka and is often seen at protests and functions concerning Tamil Eelam nationalism around the world.
