[CentOS] Change bash colours like in VIM

In VIM one can easily change colours with ":set backgorund=dark". This
doesn't actually change the background, but rather uses a colour
scheme that is designed for a dark background. Is there any quick
command like this for bash? I don't want to edit the whole config file
if there is a quick way to get a better colour scheme.

Thanks.
