Dear Uncle Dixer: What is the lucky roof color for the addresses 422 and 632? Best regards. 

Answer: 422 is a very Yin number, so you would need some bright color to balance it, like yellow/orange terracotta roof tiles.

632 has more Yang numbers (odd numbers) than Yin (even numbers), so I would use a darker color tiles like natural slate.

Generally speaking, a brighter color for house 422 and a more subdued color for house 632. If you can use a natural material, it’ll be luckier than an artificial one because being natural it goes with the Chinese philosophy of “Wu-Wei”. It is a “technique by means which one who practice it may gain enhanced control of human affairs”, according to Wikipedia.
