Help! Somehow my terminal looks like this:
It's nearly impossible to read the text. How can I fix it without exiting the terminal?

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:
According to the manpage:
init If the terminfo database is present and an entry for the user's terminal exists (see -Ttype, above), the following will occur: (1) if present, the terminal's initialization strings will be output as detailed in the terminfo(5) section on Tabs and Initialization, (2) any delays (e.g., newline) specified in the entry will be 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 skipped.
This should restore your terminal to its original colors.
