One day I decided that the terminal of Mac OS X was too dull without colors. Intially, I updated my .bash_profile. It looks something like:
alias ls='ls -G' alias ll='ls -l' PS1="\[33[1;34m\]\h\[33[0m\]:\W \$ "
Well, pretty good start I guess. But the default colors were an eyesoar, so an alternative would be to turn off colors again and move back to were I started. I did not want to do that. So I found a litte program called TerminalColours, which allows one to replace the colors.
This is what it looks like!
