The way people react to colors is due to a mix of physiological, sociological, and spiritual factors. What works in one society does not always work in another. Likewise, the knowledge that has come out of the mystery schools often needs to be adjusted to apply to modern tastes. What we present here is our own color theory drawn from personal studies and experience. What is helpful to remember about the differences between the Western and Asian systems of color theory is that in the West, the favorite planets generally are Jupiter and Venus, which are expanders, and relate to luck and luxury. From the Earth, both have a blue tone. For the Chinese, the favorite planets are Saturn, a pale yellow planet that is the stabilizer, and Mercury, the silver planet that deals with commerce and children. We might say that, culturally, the difference is a focus upon possibilities versus responsibilities. Surveys have shown that the favorite color of Americans is blue, while their least favorite is yellow. This highlights yet another difference, which necessitates the adjustment of systems when practicing Feng Shui in the west.
