Favour a balance between bright Yang colours and soft Yin colours.
Red and blue colours should be avoided in the bedrooms. Red should be avoided in the kitchen. White represents all colours in Feng Shui. Avoid stripes on walls and curtains...
Lights: It is preferable to use indirect lights rather than big lights (neon...), use salt or selenite lamp to purify the atmosphere. Scented candles give the space a refined note.
Materials: Favour natural materials (wool, cotton, linen, wood, stone...).
Shapes: Soft and rounded shapes (furniture, table, rounded pillar) are preferable to protruding angles that bring the Shar Qi.
