A black body or blackbody is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. The radiation emitted by a black body in thermal equilibrium with its environment is called black-body radiation. The name "black body" is given because it absorbs all colors of light.
The CMYK model adds a black primary to improve the darkness of blacks, where the CMY model can only mix to dark gray or only achieves black inefficiently, i.e. by using lots of the primary pigments. In the CMY model, an equal mixture of cyan and magenta is blue , an equal mixture of magenta and yellow is red and an equal mixture of yellow and ...

The use of such materials, often in the form of tiles viewed in a sensory room under UV light, is common in the United Kingdom for the education of students with profound and multiple ...
In color theory, hue is one of the main properties (called color appearance parameters) of a color, defined technically in the CIECAM02 model as "the degree to which a stimulus can be described as similar to or different from stimuli that are described as red, orange, yellow, green, blue, violet," [1] within certain theories of color vision.
Video black level is defined as the level of brightness at the darkest (black) part of a visual image or the level of brightness at which no light is emitted from a screen, resulting in a pure black screen. Video displays generally need to be calibrated so that the displayed black is true to the black information in the video signal. If the ...
For example, RGB images are composed of three independent channels for red, green and blue primary color components; CMYK images have four channels for cyan, magenta, yellow and black ink plates, etc. Here is an example of color channel splitting of a full RGB color image.
Black and burst, also known as bi-level sync and black burst, is an analogue signal used in broadcasting. It is a composite video signal with a black picture. [1] It is a reference signal used to synchronise video equipment, in order to have them output video signals with the same timing. This allows seamless switching between two video signals.
