It came to English through French from the Latin word tenebrosus, itself derived from tenebrae, meaning, according to the Oxford Latin Dictionary, “the more or less complete absence of light, darkness,” “the darkness of night,” and “(as of squalid or disreputable buildings, etc.)

Tenebrism is used only to obtain a dramatic impact while chiaroscuro is a broader term, also covering the use of less extreme contrasts of light to enhance the illusion of three-dimensionality. The term is somewhat vague, and tends to be avoided by modern art historians.

Here are some adjectives for darkness: enormous uncanny, soon actual, cool chemical, cold and impregnable, blank clear, warm, numbing, weary and secretive, peculiarly textured, savage and impenetrable, unprotected, unsuspecting, thick, magical, muddy, windy, vast and horrifying, viscous, sentient, dense and frightful.

There is no scientific definition of darkness because darkness doesn’t exist. Light exists, and that is all. There is more light or less light. People gave a name to the absence of light, and they called it darkness. Darkness, like everything that people vulgarized, is relative.

Now coming to the point,darkness looks black in color because it’s frequency is capable of absorbing all colors of light and hence black. Unlike white it doesn’t reflect other colors. Darkness is absence of any color. that is why we are able to see universe at least,which is black in color.

Noun. 1. total darkness – total absence of light; “they fumbled around in total darkness”; “in the black of night” lightlessness, pitch blackness, black, blackness. dark, darkness – absence of light or illumination.

Rhodopsin is the photopigment used by the rods and is the key to night vision. Intense light causes these pigments to decompose reducing sensitivity to dim light. Darkness causes the molecules to regenerate in a process called “ dark adaptation” in which the eye adjusts to see in the low lighting conditions.

First of all, it is impossible to see anything at all in total darkness. Total darkness means the absence of light, and our eyes depend on light to see. With enough time, our eyes can adapt and see the low levels of light present in partial darkness.

The human eye and brain together translate light into color. Light receptors within the eye transmit messages to the brain, which produces the familiar sensations of color. By varying the amount of red, green and blue light, all of the colors in the visible spectrum can be produced.

Human tetrachromats cannot see beyond the normal visible light spectrum, but instead have an extra photoreceptor that is most sensitive to colour in the scale between red and green, making them more sensitive to all colours within the normal human range.

These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones. The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are not good for color vision.

Scientifically, color is an expression of light. Certain materials absorb and reflect specific wavelengths of visible light, which results in objects taking on a certain color to the human eye. When nearly all light is reflected, you see white. When no light is reflected, you see black.
