@FriendlyGhost wins this round!
This popped into my head earlier today, but I had to wait to get home to do it:
The Anarchic Sea
Although anarchism, almost by definition, does not have one overriding symbol or colour, the one which has been used the most by its adherents since the mid 19th century is the symbol of dark blue waves under a light blue sky. Its origin is disputed, with some claiming it was first designed by an early anarchist group from the west coast of France, inspired by the chaos of the Bay of Biscay, whilst others claim that it originated in either Poland or Prussia, inspired by storms on the Baltic coasts. Regardless of the exact origin, it is universally acknowledged that the chaos of the sea, which cannot be tamed by any human intervention or government dictat, is a perfect analogy for anarchism. Critics who point out that putting light blue and dark blue together violates the normal rules of flag making generally receive a response similar to "dude, that's the whole point"...
