I want to distinguish my command from the rest of the output of the shell easily through different colors. But I don't have much experience with customizing my bash shell, so I don't know how to reset the color (after) my input.

my current PS1 variable looks like this:

export PS1="$redu$green$(__git_ps1) $turkw
$white$ "

# '$(__git_ps1)' git status prompt (generates a space before it even if empty)

So my input is white. But even the output of the commands is white because it is not reset. Furthermore, if the command itself color codes its output, then it itself resets the colors which result in some ugly mixing of white and gray.

So how do I reset the color after my input command?

The DEBUG trap runs before each command, so you can abuse it to reset the colors, if you have colored the command line input. ("abuse" since this isn't debugging.)

With this:

$ promptcol="$(tput sgr0)$(tput setaf 3)"
$ cmdcol="$(tput sgr0)$(tput bold)"
$ normalcol="$(tput sgr0)"
$ trap 'echo -n "$normalcol"' DEBUG
$ PS1="[$promptcol]w$ [$cmdcol]"

I get this:

Note that you need the [...] surrounding the color codes, so that the shell knows how to calculate the width of the prompt properly. Also, note that you can't put the [...] within the variables, the shell handles the prompt escapes first, and variable expansions only after that.

On the ~/.bash_logout Insert the following:

echo -e "33[0m"
/usr/bin/clear
