Hi Melanie,,
#7 is associated with metal according the the 8 directions. But the year number is only used to determine your favourable and unfavourable directions.
Just check the list, find your year and the associated fortune element. In my old edition the explanation can be found on page 32 of level 1 (Love Diamond Facet - Rose): "Your fortune element can help you determine the best colors for you. Use them in your environment and clothing."
