caption_attribution_description: English: All 16,777,216 colors of 24-bit RGB palette (truecolor) in a 4096 × 4096 bitmap. This image was made by copying Image:Greenblue.png 256 (technically 81) times into a 16x16 grid then adding a resized 16 × 16 to a 256 × 256 additive layer of black to red increasing from left-to-right, descending, above the original 16x16 grid of Image:Greenblue.png. This image follows a different pattern than Image:16777216colors.png
context_page_description: This list of monochrome and RGB palettes includes generic repertoires of colors to produce black-and-white and RGB color pictures by a computer's display hardware, 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.
  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 rendered with that palette are given. The test chart shows the full 256 levels of the red, green, and blue primary colors and cyan, magenta, and yellow complementary colors, along with a full 256-level grayscale. Gradients of RGB intermediate colors, and a full hue spectrum are also present. Color charts are not gamma corrected.
context_section_description: Often known as truecolor and millions of colors, 24-bit color is the highest color depth normally used, and is available on most modern display systems and software. Its color palette contains (2⁸)³ = 256³ = 16,777,216 colors. 24-bit color can be represented with six hexadecimal digits. This is approximately the number of individual colors the human eye can distinguish within the limited gamut of a typical display.
  The complete palette (shown above) needs a squared image of 4,096 pixels wide (50.33 MB uncompressed), and there is not enough room in this page to show it at full.
  This can be imagined as 256 stacked squares like the following, every one of them having the same given value for the red component, from 0 to 255.
  The color transitions in these patches must be seen as continuous. If you see color stepping (banding) inside, then probably your display is using a Highcolor (15- or 16- bits RGB, 32,768 or 65,536 colors) mode or lesser.
  This is also the number of colors used in true color image files, like Truevision TGA, TIFF, JPEG (the last internally encoded as YCbCr) and Windows Bitmap, captured with scanners and digital cameras, as well as those created with 3D computer graphics software.
  24-bit RGB systems include:
  Amiga Advanced Graphics Architecture (256 or 262144 colors)
  Nintendo 3DS
  PlayStation
  PlayStation Vita
  Later models of Super VGA (SVGA) IBM PC compatible graphic cards
  Truevision AT-Vista graphic cards for IBM PC/AT and compatibles, and NU-Vista for Apple Macintosh.
  The Philips CD-i
  Nintendo Switch
