Following a request by Michal Hospodár, follower of this blog and a "netfriend", I made a first attempt to a flag representing the Yi (or Lolo) people that inhabits China, Vietnam and Thailand. I have to admit that it took some weeks before a decent idea came to me.
The Yi people suffers from an absence of own vexillology, so I had to start from zero. The inspiration that I cited are some ethnic Yi female folkloric costumes, with examples here, here and here. They all are black, with pink flowers. As I can't identify the specie of flower, I used lotus, common in Chinese vexillology (Macau, for example) and is a good shot. Here is the flag:
Although black and pink, in theory, isn't a good color combination to flags, well-chose shades can make a nice result. An alternative depiction is as follow:
Your comments are welcome.
This flag is made, in part, for scholar purposes, as ethnic flags on China are still officially banished, as far as I know.
