Quattron

Quattron is the brand name of an LCD color display technology produced by Sharp Electronics. In addition to the standard RGB (Red, Green and Blue) color subpixels, the technology utilizes a yellow fourth color subpixel (RGBY) which Sharp claims increases the range of displayable colors, and which may mimic more…

Multi-primary color display

Multi-primary color (MPC) display is a display that can reproduce a wider gamut color than conventional displays. In addition to the standard RGB (Red Green and Blue) color subpixels, the technology utilizes additional colors, such as yellow, magenta and cyan, and thus increases the range of displayable colors that the…

Hold-And-Modify

Hold-And-Modify, usually abbreviated as HAM, is a display mode of the Commodore Amiga computer. It uses a highly unusual technique to express the color of pixels, allowing many more colors to appear on screen than would otherwise be possible. HAM mode was commonly used to display digitized photographs or video…

High color

High color graphics (variously spelled Highcolor, Hicolor, Hi-color, Hicolour, and Highcolour, and known as Thousands of colors on a Macintosh) is a method of storing image information in a computer’s memory such that each pixel is represented by two bytes. Usually the color is represented by all 16 bits, but…

Amiga Halfbrite mode

Extra Half-Brite (EHB) mode is a planar display mode of the Commodore Amiga computer. It uses six bitplanes (six bits/pixel). The first five bitplanes index 32 colors selected from a 12-bit color space (4096 possible colors). If the bit on the sixth bitplane is set the display hardware halves the…

8-bit color

8-bit color graphics is a method of storing image information in a computer’s memory or in an image file, such that each pixel is represented by one 8-bit byte. The maximum number of colors that can be displayed at any one time is 256. There are two forms of 8-bit…

Binary image

A binary image is a digital image that has only two possible values for each pixel. Typically, the two colors used for a binary image are black and white. The color used for the object(s) in the image is the foreground color while the rest of the image is the…

Monochrome

Monochrome describes paintings, drawings, design, or photographs in one color or values of one color. A monochromatic object or image reflects colors in shades of limited colors or hues. Images using only shades of grey (with or without black or white) are called grayscale or black-and-white. However, scientifically speaking, monochromatic…

Grayscale

In photography, computing, and colorimetry, a grayscale or greyscale 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. Images of this sort, also known as black-and-white or monochrome, are composed exclusively of…

Palette in computing

In computer graphics, a palette is a finite set of colors. Palettes can be optimized to improve image accuracy in the presence of software or hardware constraints. Terminology An adaptive color palette expanding from 2 colors to 256 colors, demonstrating how the image changes (click to see animation). Depending on…

Color depth

Color depth, also known as bit depth, is either the number of bits used to indicate the color of a single pixel, in a bitmapped image or video frame buffer, or the number of bits used for each color component of a single pixel. For consumer video standards, such as…
