Setting the colors of file types in ls

See for a good overview about how the colors used by ls are specified.

In my Cygwin .bashrc file, I put

alias ls='ls --color=auto'
alias ll='ls -l'
export LS_COLORS

In the third line, di=34 sets directory names to blue, ln=35 sets symlinks to purple (default is to set it to 36 which is cyan and looks bad on white background).
