Vision Test Chart

(February 2008) () For a full listing of computer's color palettes, see This list of monochrome and RGB palettes includes generic repertoires of colors () to produce and color pictures by a computer's display, not necessarily the total number of such colors that can be simultaneously displayed in a given text or graphic mode of any machine. 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 given maximum number of levels per component. For specific hardware and different methods to produce colors other than RGB, see the, the and the.

For various software arrangements and sorts of colors, including other possible full RGB arrangements within 8-bit displays, see the. Each palette is represented by a series of color patches. When the number of colors is low, a 1-pixel-size version of the palette appears below it, for easily comparing relative palette sizes.

Huge palettes are given directly in one-color-per-pixel color patches. For each unique palette, an image color test chart and sample image ( original follows) rendered with that palette (without ) are given. The test chart shows the full 256 levels of the red, green, and blue (RGB) primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors (orange, lime green, sea green, sky blue, violet, and fuchsia), and a full spectrum are also present. Color charts are not corrected. These elements illustrate the color depth and distribution of the colors of any given palette, and the sample image indicates how the color selection of such palettes could represent real-life images.

These images are not necessarily representative of how the image would be displayed on the original graphics hardware, as the hardware may have additional limitations regarding the maximum display, and color placement. For simulated sample images for notable computers, see the and articles.

The general rule is that those palettes have 2 n different shades of gray, where n is the number of bits needed to represent a single. Monochrome (1-bit) [ ] graphics displays typically have a black background with a white or light gray image, though green and amber were also common. Such a palette requires only one bit per pixel. Where photo-realism was desired, these early computer systems had a heavy reliance on to make up for the limits of the technology.

In some systems, as and graphic cards for the, a bit value of 1 represents white pixels (light on) and a value of 0 the black ones (light off); others, like the and with monochrome monitors, a bit value of 0 means a white pixel (no ink) and a value of 1 means a black pixel (dot of ink), which it approximates to the printing logic. 2-bit Grayscale [ ] In a 2-bit color palette each pixel's value is represented by 2 bits resulting in a 4-value palette (2 2 = 4). 2-bit dithering: It has black, white and two intermediate levels of gray as follows: A monochrome 2-bit palette is used on: •, and monochrome graphic displays. • Original system portable. • monochrome LC displays. • with A2024 monochrome monitor in high-resolution mode. • The original • The original.
