The likely cause of this problem are ANSI Escape Codes. These allow scripts to change the foreground and background color of the terminal. You can even mimic the colors of the screenshot above by running the following command:

echo -e '\E[32;46m'

To reset the terminal colors, use the following command:

tput init

              set in the tty driver,

          (3) tabs expansion will be turned on or off according to the
              specification in the entry, and

          (4) if tabs are not  expanded, standard  tabs  will  be  set
              (every 8 spaces).

          If an entry does not contain the information needed for any of
          the four above activities, that activity will silently be

This should restore your terminal to its original colors.
