For age is opportunity no less than youth itself, though in another dress, and as the evening twilight fades away, the sky is filled with stars, invisible by day. – Henry Wadsworth Longfellow

A few amber clouds floated in the sky without a breath of air to move them. The horizon was of a fine golden tint, changing gradually into a pure apple-green, and from that into the deep blue of the mid-heaven. – Washington Irving, “The Legend of Sleepy Hollow”

The sky was a midnight-blue, like warm, deep, blue water, and the moon seemed to lie on it like a water-lily, floating forward with an invisible current. – Willa Sibert Cather
