A black band to represent the people. Red for their connection to land. A yellow circle in the centre for the sun.
This is the design of the Aboriginal flag, which is seen all over Australia - atop bridges and buildings, painted on walls, printed on T-shirts.
Originally a protest flag, it's now recognised as the dominant symbol of Australia's Aboriginal people and is an official flag of the country.
So when it emerged last year that some Aboriginal people had been ordered to stop using it, many were confounded. Few people had known the flag was constrained by copyright laws.
Currently, even Aboriginal groups must pay a non-Aboriginal-run business to reproduce the flag on clothing and merchandise.
The situation has angered many people. Indigenous MP Linda Burney - who has the flag tattooed on her arm - has declared the symbol is being "held hostage".
Amid increasing pressure, Australia's government is now reported to be considering taking over the copyright, but it faces complex legal and cultural issues.
