export PS1="\[$(tput setaf 226)\]\u\[$(tput setaf 220)\]@\[$(tput setaf 214)\]\h \[$(tput setaf 33)\]\w \[$(tput sgr0)\]$ "

Bash prompt PS1

To use the colors you chose, set the PS1 environment variable in your shell:

export PS1="\[$(tput setaf 226)\]\u\[$(tput setaf 220)\]@\[$(tput setaf 214)\]\h \[$(tput setaf 33)\]\w \[$(tput sgr0)\]$ "export PS1="\[\e[38;5;226m\]\u\[\e[38;5;220m\]@\[\e[38;5;214m\]\h \[\e[38;5;33m\]\w \[\033[0m\]$ "

It's up to you to decide between tput and ANSI escape sequences. To persist your customized prompt, export PS1 in ~/.bashrc or ~/.bash_profile

Bash prompt variables

These are the variable substitutions used above.

\u     user
\h     hostname
\w     ~/path/to/directory

For reference, this is a list of all the valid bash prompt variables from the PROMPTING section in the bash man pages in `man bash`

\a     an ASCII bell character (07)
\d     the date in "Weekday Month Date" format (e.g., "Tue
       May 26")
\D{format}
       the format is passed to strftime(3) and the result
       is inserted into the prompt string; an empty format
       results in a locale-specific time representation.
       The braces are required
\e     an ASCII escape character (033)
\h     the hostname up to the first `.'
\H     the hostname
\j     the number of jobs currently managed by the shell
\l     the basename of the shell's terminal device name
\n     newline
\r     carriage return
\s     the name of the shell, the basename of $0 (the
       portion following the final slash)
\t     the current time in 24-hour HH:MM:SS format
\T     the current time in 12-hour HH:MM:SS format
\@     the current time in 12-hour am/pm format
\A     the current time in 24-hour HH:MM format
\u     the username of the current user
\v     the version of bash (e.g., 2.00)

       2.00.0)
\w     the current working directory, with $HOME
       abbreviated with a tilde (uses the value of the
       PROMPT_DIRTRIM variable)
\W     the basename of the current working directory, with
       $HOME abbreviated with a tilde
\!     the history number of this command
\#     the command number of this command
\$     if the effective UID is 0, a #, otherwise a $
\nnn   the character corresponding to the octal number nnn
\\     a backslash
\[     begin a sequence of non-printing characters, which
       could be used to embed a terminal control sequence
       into the prompt
