Well, three notes are in order:
1. The exact colors are user configurable (via the LS_COLORS env var or
otherwise) and may vary from distribution to distribution or from system
to system.
2. ls can color files which match a certain glob in different colors, like
*.zip or *.gz. This is a coloring that is only a convenience and does not
indicate that the file is special in any way. (it may also not belong to
its correct type).
3. colors can be misleading. For example, on my Mandrake system, all files
ending with .sh are colored green (which is the same color for
exacutables) even if they are not executable. I remember trying to execute
a shell script I prepared because I saw its color was green (./upload.sh)
only to discover it was not executable as far as its permissions were
concerned.
