Color scheme
Using"seven precious woods"textures as canvas and natural light as ink, creating"sixteen breathing colors"that interpret the symbiotic aesthetics of human civilization. Each wood grain represents a slice of civilizational evolution, dissolving Eastern and Western aesthetic boundaries through color, transforming doors and windows into cultural vessels carrying shared human memories, achieving the realm of "seeing the universe in wood grains".
UsingDutch-importedSIKKENS water-based paint, with plant-based emulsion capturing the breathing texture of wood grains. Eco-friendly molecules unfold in sunlight, creating a baby-safe touch that transforms each window into a living home art piece.
