Does any country in the world have the color purple on its flag?

Only one of the current national flags has the color "purple" : the flag of Dominica includes a Sisserou Parrot, which should be depicted as green and purple. (Some renditions use a paler color that has more blue.)

Other flags that prominently include actual "purple" or "lilac" :

• Flag of the republic of Chuvashia in the Russia Federation
• Flag of the Balearic Islands (Spain)
• Flag of Málaga (city in Andalusia, Spain)
• Flag of Montreal
