Web surfers are tough on sites. Even covering a slow moving
subject area (eg grass growing, paint drying) the pressure is on to update
daily. This routine will change your background color each day of the
week, creating the illusion of rampant activity and making the site look
fresh each day. Call it with a list of the colors you want for each day,
starting with Monday. Supply colors as rgb values (eg "#ffffff") or as
color names (eg "white").
