Hello, I just recently bought a new house with stucco exterior. The roof tiles are dark grey and the exterior paint is a pastel greyish/blue with soft white square designs around the front pillar and one white solid line around the entire house, symbolically they appear to be square representing "metal". In my opinion the roof represents 'water', the walls represents 'metal' and the soft white square design represents 'metal'. Is this a bad Feng Shui combination or would it be better to paint the exterior walls a sage green with soft beige trim (square designs)? So that 'water' is over 'tree' or 'green'?
