When I made this flag, I used red to symbolize the violent history of the Kansas Territory, a yellow stripe at the bottom to evoke a wheat field (given that one of Kansas's nicknames is the Wheat State), and a sunflower at the top left. I didn't notice the communist connotation of a red flag with a yellow symbol in the canton until someone pointed it out back when I posted this on Reddit. I still really like how the design looks, though maybe it'd be best to change the red to blue.

Kansas welcomes you, Komrade!

Hearts of Iron IV has an "America Divided" mod where all the states are treated as independent nations. So they had to find or create flags for democratic, communist and facist political paths. This would be right at home there!
