All Ansi 256 Colors

I created this resource to help visualize the color options available for 256 color terminal emulators.

The included all-ansi-colors-pretty.html file offers a simple and quick way of scrolling through all of the 65536 possible ANSI 256-color foreground/background color combinations.

Given that viewing ~65k color combinations takes lots of screen space and is resource intensive to output in a terminal emulator, it's best to view them in a web browser, hence the included HTML file:

The shell script, all-ansi-256-colors.sh was used to generate generate the all of the colours as console output.

The console output was converted to an HTML file for easy browsing using the following commands (requires ansi2html):

chmod +x all-ansi-256-colors.sh 
# The following command may take a few seconds to a few minutes to run.
./all-ansi-256-colors.sh | ansi2html > all-ansi-256-colors.html

A pre-generated HTML file is included in the repository all-ansi-256-colors.html. The "pretty" version, all-ansi-256-colors-pretty.html includes buttons that you can click to toggle bold, italics, and underlines of the text since most terminal emulators support those styles.

Note: Forground/Background colors 0-16 may not look the same in your setup because those colors are defined in terminal emulator settings.
