### Using ANSI Color
ANSI-Colors can easily be used in the shell by using the control sequences as described by
[techstop](https://techstop.github.io/bash-script-colors).
Each color has an own sequence and can be combined to affect the background.
Additionally the font can also be changed using these control sequences.
The following code displays the sequences and makes the control sequences be available from
variables.
```sh
red="\e[0;91m"
blue="\e[0;94m"
expand_bg="\e[K"
blue_bg="\e[0;104m${expand_bg}"
red_bg="\e[0;101m${expand_bg}"
green_bg="\e[0;102m${expand_bg}"
green="\e[0;92m"
white="\e[0;97m"
bold="\e[1m"
uline="\e[4m"
reset="\e[0m"
```
