Customize bash prompt

[Yigit Akoymak]

*Greetings,*

I just installed a GNU/linux distro,Guix, in my virtualbox without X 
server so there is only bash promt available , however I can't 
understand how I can change color of the bash prompt for exmaple I want 
$ sign to be green ,other text to red and background to blue.Also I read 
the Bash refence manual at gnu.org no luck and surfed in forums on the 
web that have diffrent aproache so it confused me a lot |¯\_(⊙︿⊙)_/¯.I 
would be very happy if you forward me the documenatation or tutorial to me.|
