There is color in the sky that most of us can see. It's the color that comes in the morning only to end in at night. But that's a lie. Because the night is dark with a circle of light, but look a little deeper into the meaning. There is light in the dark, there is optimism in the sea of pessimism.
But there could be a smidge of pessimism in optimism. The sky in the day, so bright with blue, sure it has light, but that light is a clue. A clue that heeds us away from it's literal meaning. Look at it, it hurts to look, it's too bright.
