What do the colors symbolize?
What aspects of En-Uk do they symbolize?If that were my flag, the flag of Kevinistan, I might write something like this:Green = the glorious pasturelands of Kevinistan, upon which roam our magnificent, powerful sheep, goats and cows! Loyalty is in their blood!Blue = the skies above Kevinistan: always benevolent, never stormy!Black = the darkness of our hearts... because Kevinistan's citizens are all vampires and zombies!Red = the impure blood of our enemies, which flows into our tilled fields when they dare to attack us! (Also, the blood of our cows, sheep, and goats whenever there's no enemy blood to suck.)
(Not sure whether En-Uk might catch the reference to La Marseillaise.)
