On most Linux distributions, “ls” prints directories in dark blue text. Run an X terminal (such as XTerm) in reverse video, and you get directories in dark-blue-on-black text. I decided that anything would be better, and started looking for solutions. The first solution I found was Solarized.
The results as you can see, are pleasant. They are also consistent enough not to cause offence.
