how to install colorama in kali linux

Installing with pip is almost always the way to go. 
It will handle downloading the package for you, as well as any dependencies. 
If you do not have pip, 
see http://www.pip-installer.org/en/latest/installing.html.

Then

pip install colorama
or
sudo pip install colorama

Ba-boom! Done.
