Black. Black is a primary color across all models of color space. In Western culture, it is considered a negative color and usually symbolizes death, grief, or evil but also depression. People often wear black for mourning, although this practice is not as widespread as it was in the past. White
The contrast of white and black ( light and darkness, day and night) has a long tradition of metaphorical usage, traceable to the Ancient Near East, and explicitly in the Pythagorean Table of Opposites . In Western culture as well as in Confucianism, the contrast symbolizes the moral dichotomy of good and evil .
In computing terminology, black-and-white is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of gray, is referred to in this context as grayscale.
Of an image, the term monochrome is usually taken to mean the same as black and white or, more likely, grayscale, but may also be used to refer to other combinations containing only tones of a single color, such as green -and-white or green-and-red.
Black and white have long been known to combine "well" with almost any other colors; black decreases the apparent saturation or brightness of colors paired with it and white shows off all hues to equal effect.

In digital photography, computer-generated imagery, and colorimetry, a grayscale image is one in which the value of each pixel is a single sample representing only an amount of light; that is, it carries only intensity information. Grayscale images, a kind of black-and-white or gray monochrome, are composed exclusively of shades of gray.
HTML/CSS [1] B: Normalized to [0–255] (byte) H: Normalized to [0–100] (hundred) Black is a color that results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and grey. [2] It is often used symbolically or figuratively to represent darkness. [3]
Monochrome photography is photography where each position on an image can record and show a different amount of light, but not a different hue. It includes all forms of black-and-white photography, which produce images containing shades of neutral grey ranging from black to white. [1]
A dominant theory of color vision proposes that color information is transmitted out of the eye by three opponent processes, or opponent channels, each constructed from the raw output of the cones: a red–green channel, a blue–yellow channel, and a black–white "luminance" channel. This theory has been supported by neurobiology, and ...
