ANSI Escape Codes

When you work in the terminal (e.g. on Unix ), having colors and text formatting often improves the user experience.

There is a great post on Stack Overflow called List of ANSI color escape sequences which goes into detail on all supported escape codes.

Here is a basic selection:

Code Usage
\033[1m Bold
\033[3m Italic
\033[4m Underline
\033[38;2;<r>;<g>;<b>m Set RGB foreground color
\033[48;2;<r>;<g>;<b>m Set RGB background color

There’s a list of terminals that support RGB, most importantly and Hyper don’t support it while iTerm2 , Alacritty and PuTTY support it (check the link for an exhaustive list).
