Color and TTYs are a two-edged sword. The combinations are simple commands for foreground and background color, but there is no intelligent (read: automatic!) use of foreground color against different colored backgrounds to increase readability. For example. The CLI consoles on my Linux machine have a black background. My normal xterms in the GUI windows use a white background. The use of specific colors when 'ls' is used works well on the white xterm background. But against the CLI consoles the dark-blue on black directory-color can often be extremely hard to read.
