ls output that you can actually read.
PuTTY is a fine terminal emulator for Windows. However, the default colours are rather dark. In particular, I hear lots of grumbles that the navy blue directory names used by GNU ls are practically unreadable against the black background.
I find the following colours much easier on the eye. They are the same colours that you once got by default in Gnome on Linux.
Want these colours for any terminal? See termcolours.
