“I thought of Gatsby’s wonder when he first picked out the green light at the end of Daisy’s dock. He had he had come a long way across this blue lawn, and his dream must have seemed so close that he could hardly fail to grasp it.” (The Great Gatsby, pg. 180)

Gatsby had chosen his house strictly across the bay from Daisy’s. The green light was the only visible thing, his only memory of her. The light states Daisy’s obsession for money and how Gatsby will become obsessed with it to suit her way of living when she comes back.

The blue lawn is the vast ocean that divides them and the green lantern at the other side can also be seen as the gold pot after the rainbow. How Gatsby may pursuit it and try to reach it but every time he comes close to it he will not find anything.
