To permanently enable pretty list colors in the terminal, first enter this command:
nano ~/.profile
Once in nano, add the following line to your profile:
export CLICOLOR=1
If, like me, you like to use a dark background in terminal, also add this line. It’ll lighten up the unreadable blue used for directories:
export LSCOLORS=Hxfxcxdxbxegedabagacad
