Editing ANSI escape code (section)

==== 3-bit and 4-bit ====

The original specification only had 8 colors, and just gave them names. The SGR parameters 30–37 selected the foreground color, while 40–47 selected the background. Quite a few terminals implemented "bold" (SGR code 1) as a brighter color rather than a different font, thus providing 8 additional foreground colors. Usually you could not get these as background colors, though sometimes inverse video (SGR code 7) would allow that. Examples: to get black letters on white background use {{code|ESC[30;47m}}, to get red use {{code|ESC[31m}}, to get bright red use {{code|ESC[1;31m}}. To reset colors to their defaults, use {{code|ESC[39;49m}} (not supported on some terminals), or reset all attributes with {{code|ESC[0m}}. Later terminals added the ability to directly specify the "bright" colors with 90–97 and 100–107.

The chart below shows a few examples of how VGA standard and modern [[terminal emulator]]s translate the 4-bit color codes into 24-bit color codes.
