The Eastern zone is characterized by the element of WOOD. To energize the East, use GREENS and BLUES as much as possible.
Eastern energies are superb for inspiring optimism, contentment and material & spiritual growth. The whole ambience of the East encourages an individual to plan the future with an affirmative and positive mindset. This zone is thus suited for use as studies and home offices.
Plants and water features in this zone will also enhance the good energies of this part of the house (This is a quote from Lillian Too and the wofs home page.)
