The color green and it's symbolism in the great gatsby

• The color green symbolizes hope
• Gatsby was hoping to restore his ancient relationship with Daisy that has long been impossible, though Gatsby failed to realize it because he was blinded by the hope generated by the green light. It insinuates that hope is not always a reality. 
• Nick encounters Gatsby standing in Gatsby’s lawn in the dead of night, and describes what he sees “…he stretched out his arms towards the dark water in a curious way, and, far as I was from him I could have sworn he was trembling involuntarily I glanced seaward – and distinguishing nothing except a single green light, minute and faraway, that might have been the end of a dock.
