ISCC–NBS descriptor. Black. B: Normalized to [0–255] (byte) Black. #000000. Black is a color, the perception of which is evoked by the total absence of light that stimulates any of the three types of color sensitive cone cells in the human eye and with very low brightness compared to the surroundings.
Black is the darkest shade, and the result of the absence or complete absorption of light. Like white and gray, it is an achromatic color, literally a color without hue.
The first letter of the color code is matched by order of increasing magnitude. The electronic color codes, in order, are: 0 = Black; 1 = Brown; 2 = Red; 3 = Orange; 4 = Yellow; 5 = Green; 6 = Blue; 7 = Violet; 8 = Gray; 9 = White. Easy to remember. A mnemonic which includes color name(s) generally reduces the chances of confusing black and brown.
The IALA recommends categorical color codes in 7 colors: red, orange, yellow, green, blue, white & black. [4] Adding redundant coding of luminosity and colorfulness adds information and increases speed and accuracy of color decoding tasks. [3]

An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
In additive color models, such as RGB, white is the "additive" combination of all primary colored lights, and black is the absence of color. In the CMYK model, it is the opposite: white is the natural color of the paper or other background, black results from a full combination of colored inks.
The Black Codes, sometimes called the Black Laws, were laws which governed the conduct of African Americans (both free and freedmen ). In 1832, James Kent wrote that "in most of the United States, there is a distinction in respect to political privileges, between free white persons and free colored persons of African blood; and in no part of ...
This list of monochrome and RGB palettes includes generic repertoires of colors (color palettes) to produce black-and-white and RGB color pictures by a computer's display hardware. RGB is the most common method to produce colors for displays; so these complete RGB color repertoires have every possible combination of R-G-B triplets within any ...
