Darkness, as polar to brightness, is understood to be an absence of visible light. It is also the appearance of black in a color space.
Humans are unable to distinguish color when either light or darkness predominate (W. Wundt, Outlines of Psychology, 1907). In the absence of light, perception is achromatic and ultimately, black.
The emotional response to darkness has metaphorical connotations in many cultures.
Famous quotes containing the word darkness:
“Look at your lake, Christine. You’ll love it here, when you get used to the dark. And you’ll love the dark, too. It’s friendly. And peaceful. It brings rest and relief from pain. It’s right under the Opera. The music comes down and the darkness distills it, cleanses it of the suffering that made it, then it’s all beauty and life here is like a resurrection.”
—Eric Taylor, and Leroux. Arthur Lubin. Erique Claudin (Claude Rains)
“I falter where I firmly trod,
And falling with my weight of cares
Upon the great world’s altar-stairs
That slope thro’ darkness up to God,”
—Alfred Tennyson (1809–1892)
“Stretch out your hand toward heaven so that there may be darkness over the land of Egypt, a darkness that can be felt.”
—Bible: Hebrew, Exodus 10:21.
