freebsd colorful you terminal that also work great on putty

install the gnuls (gnu ls) port in /usr/ports/misc/gnuls. I think the colors are much nicer.
After the install, type: gnuls --color The command is long- so the way I handle this is to write a script called lls continaing the command gnuls --color and I put it in /usr/local/bin. I then chmod the command for execute by all (chmod 755 /usr/local/bin/lls). You can set the permissions to your taste.

or just

echo "alias ls='gls --color'" >> ~/.profile
