Answer:
It describes how Sir Gawain, a knight of King Arthur's Round Table, accepts a challenge from a mysterious “Green Knight” who challenges any knight to strike him with his axe if he will take a return blow in a year and a day.
He could have chosen red for strength and power or purple for royalty and wealth, but instead he chose green. The green knight has green tinted skin and features, a green holly branch, a green axe, and a green horse. Green is known to stand for peace, restfulness, harmony, lust, love, fertility, and nature.
The Green Knight's plan is to test the court. He wants to test one of Arthur's knights. Because of their fame and how well they are known for their chivalry and courage, the Green Knight seizes this as an opportunity to place before them a challenge. Sir Gawain takes on the challenge.
