Green is the color of nature, of fortune, and of hope—and of prosperity—which is why it also represents greed, jealousy, and envy. (Goethe believed it was the color of the middle class.) The color of Shrek, the Grinch, and the Jolly Green Giant, it‘s also a color widely associated with the Irish.

The “Wearing of the Green" is an Irish street ballad that tells the story of the violent repression of supporters of the Irish rebellion of 1798. At that time, wearing green clothing was considered an act of political resistance.

There are many versions and variations, but the lyrics are consistent.

She's the most distressful country that ever yet was seen
For they're hanging men and women there for the Wearing of the Ggreen.
