The way I see it, the blue is the stuff you can't control, life's major heartbreak and struggles, that feeling of devastation so massive and brutal it inflicts permanent damage on the heart and spirit that can never be undone and will always be there, spewing somewhere in a corner of your mind like deep scars you'll have with you you're whole life. The green you also can't control. But that's the part that reminds you life is worth living. It's not the here-and-there type of good stuff that happens every day either. The green is the stuff that comes in huge doses that slap you in the face when you least expect it and brings a light to all that you are through growth, bravery, and goodness, and love. It's the stuff that picks you up when you're at the bottom and makes you keep on going even when you're sure you can't. That's the green.
