Random Riddle: She and He

She so peaceful, yet causes fear
Him so bright and full of cheer
She rests the body, he wakes the soul
Him so light, she black as coal
Her with mole and tiny bright freckles
He covers us with tiny tear speckles
She hides us, he beams with pride
He her husband, she his bride
He in bright silk, her all in velvet
A yin-yang marriage as they tell it
Two lovers who meet but twice a day
When he must go, she need stay
Now I ask you, who are they?
