The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
Orange artifact color, generated from white and black pixels, on the TRS-80 Color Computer Example of artwork created with the intent of having individual pixel values horizontally averaged over composite video. Composite artifact colors is a technique commonly used to address several graphic modes of some 1970s and 1980s home computers.
Moreover, the black point shall have the same chromaticity as the white point, yet with a luminance equal to 0.34731% of the white point luminance. [4] The ambient illumination level at the monitor faceplate when the monitor is turned off must be 32 lx. As with sRGB, the RGB component values in Adobe RGB (1998) are not proportional to the ...
This is a list of software palettes used by computers. Systems that use a 4-bit or 8-bit pixel depth can display up to 16 or 256 colors simultaneously. Many personal computers in the early 1990s displayed at most 256 different colors, freely selected by software (either by the user or by a program) from their wider hardware's RGB color palette.
This is the standard blend mode which uses the top layer alone, [3] without mixing its colors with the layer beneath it: [example needed] (,) =where a is the value of a color channel in the underlying layer, and b is that of the corresponding channel of the upper layer.
For this reason, each of the text and graphics modes has a duplicate mode which disables the composite colorburst, resulting in a black-and-white picture, but also eliminating color bleeding to produce a sharper picture. On RGBI monitors, the two versions of each mode are usually identical, with the exception of the 320 × 200 graphics mode ...
Light on dark color schemes require less energy to display on OLED displays. This positively impacts battery life and reduces energy consumption. [16]While an OLED will consume around 40% of the power of an LCD displaying an image that is primarily black, it can use more than three times as much power to display an image with a white background, such as a document or web site.

To form a color with RGB, three light beams (one red, one green, and one blue) must be superimposed (for example by emission from a black screen or by reflection from a white screen). Each of the three beams is called a component of that color, and each of them can have an arbitrary intensity, from fully off to fully on, in the mixture.
