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 hue spectrum are also present.
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.
Since Windows 95, these additional colors can be changed by the system when a color scheme needs custom colors, [ 3] reducing their utility as static, unchanging palette entries. The complete 20-color Windows system palette is: 0 — black. 246 — cream. 1 — dark red. 247 — medium grey.
This represents the least (0) to the most (255) intensity of each of the color components. Thus web colors specify colors in the 24-bit RGB color scheme. The hex triplet is formed by concatenating three bytes in hexadecimal notation, in the following order: Byte 1: red value (color type red) Byte 2: green value (color type green)
The 8-bit RGB palettes (also known as 3-3-2 bit RGB) use 3 bits for each of the red and green color components, and 2 bits for the blue component, due to the lesser sensitivity of the common human eye to this primary color. This results in an 8×8×4 = 256-color palette as follows: Red. #000000.
Initially, the limited color depth of most video hardware led to a limited color palette of 216 RGB colors, defined by the Netscape Color Cube. The web-safe color palette consists of the 216 (6 3 ) combinations of red, green, and blue where each color can take one of six values (in hexadecimal ): #00, #33, #66, #99, #CC or #FF (based on the 0 ...
List of video game console palettes. This is a full list of color palettes for notable video game console hardware. For each unique palette, an image color test chart and sample image (original True color version follows) rendered with that palette (without dithering unless otherwise noted) are given. The test chart shows the full 8-bit, 256 ...
To use a colour in a template or table you can use the hex triplet (e.g. bronze is #CD7F32) or HTML color names (e.g. red). Editors are encouraged to make use of Brewer palettes for charts, maps, and other entities, using this tool .
