Metal
The element of autumn and the west: the harvest cut, the edge, the finished thing. In a room it is roundness, hardness, whiteness and restraint.
Contracting inward
The idea
Metal is the phase of gathering in: autumn, dusk, the end of the working day. Its trigrams are Dui (the Lake, west; joy, speech) and Qian (Heaven, northwest; strength, the father). In the Wu Xing sequence it is the phase between Earth and Water: what the ground yields, and what condenses into rain.
The association with roundness is old: the circle was the shape of heaven, and metal was the material of the mirror and the coin.
In a room
Metal is the round dining table, the arched opening, the white wall, the brass tap. It brings edges into focus. Rooms with strong Metal read as precise and calm: the gallery, the well-kept kitchen, a study with nothing on the desk.
Contemporary interiors are often Metal-heavy without meaning to be: white walls, grey floors, hard surfaces, round pendant lights. The classical correction is warmth and weight, Earth’s matte clay and Fire’s light, rather than more objects.
Balance
Earth makes Metal; Metal makes Water. Fire controls Metal; Metal controls Wood. Too much Metal feels clinical; a single wooden surface at hand height, or one warm lamp, is usually enough.
