Color scheme
Using"seven precious woods"as canvas and natural light as ink, it paints"sixteen breathing colors", interpreting the symbiotic aesthetics of human civilization. Each wood grain is a slice of civilizational evolution, dissolving East-West aesthetic boundaries through color, making doors and windows cultural vessels carrying shared human memories, achieving the realm of "seeing the universe in wood grains".
UsingDutch-importedSIKKENS water-based paint, plant-based emulsion captures the breathing texture of wood grains. Eco-friendly molecules unfold in sunlight, creating a baby-safe touch that transforms each window into growing home art. As dusk filters through wooden rings, home becomes a gentle medium connecting nature and civilization.
