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 represents a slice of civilization's evolution, dissolving the boundaries between Eastern and Western aesthetics through color, making windows cultural vessels carrying shared human memories, achieving the realm of "seeing the universe in wood grains".
Using Dutch imported SIKKENS water-based paint, with plant-based emulsion capturing the breath of wood grains. The eco-friendly molecules unfold in sunlight, creating a baby-safe texture that turns each window into a growing home artwork. When dusk falls over the wooden rings, home becomes a gentle medium connecting nature and civilization.
