@X color codes are implemented in the following format:  @XBF, where the
B is the background attribute and the F is the foreground attribute,
both taken from the above table.  In other words, @XCF would be flashing
white letters on a red background.  There are two exceptions:


    @X00 - Save the current attribute
    @XFF - Recall the last attribute saved with @X00
