The Creation of Light, by Gustave Doré.
Darkness, as polar to brightness, is understood to be an absence of visible light. It is also the appearance of black in a colored space.
Humans are unable to distinguish color when either light or darkness predominateIn the absence of light, perception is achromatic and ultimately, black.
The emotional response to darkness has metaphorical connotations in many culturesThe perception of darkness differs from the mere absence of light due to the effects of after images on perception. In perceiving, the eye is active, and that part of the retina that is unstimulated produces a complementary afterimage.
"The colour of a point, on a standard 24-bit computer display, is defined by three RGB (red, green, blue) values, each ranging from 0-255. When the red, green, and blue components of a pixel are fully illuminated (255,255,255), the pixel appears white; when all three components are unilluminated (0,0,0), the pixel appears black.
Artists use darkness to emphasize and contrast with light. Darkness can be used as a counterpoint to areas of lightness to create leading lines and voids[disambiguation needed]. Such shapes draw the eye around areas of the painting. Shadows add depth and perspective to a painting. See chiaroscuro for a discussion of the uses of such contrasts in visual media.

Color paints are mixed together to create darkness, because each color absorbs certain frequencies of light. Theoretically, mixing together the three primary colors, or the three secondary colors, will absorb all visible light and create black. In practice it is difficult to prevent the mixture from taking on a brown tint.
