Color scheme
Using"seven precious woods" as the canvas and natural light as the ink, it paints"sixteen" breathing colors, interpreting the symbiotic aesthetics of human civilization, weaving a poetic world with wood grains. Each grain is a slice of civilizational evolution, dissolving the boundaries between Eastern and Western aesthetics through colors, making doors and windows cultural vessels that carry shared human memories, achieving the realm of "seeing the universe in wood grains."
UsingDutchimportedSIKKENS water-based paint, it captures the breathable texture of wood grains with plant-based emulsion. The eco-friendly molecules unfold in sunlight, creating a safe texture even a baby's skin can touch, turning each window into a growing piece of home art. When dusk spreads over the wooden rings, the home becomes a gentle medium connecting nature and civilization.
