Color scheme
Using"seven precious woods"as canvas and natural light as ink, creating"sixteen breathing colors"that interpret the symbiotic aesthetics of human civilization, weaving world poetry through wood grains. Each grain is a slice of civilization's evolution, dissolving the boundaries between Eastern and Western aesthetics through color, making windows cultural vessels that carry humanity's shared memories, achieving the realm of "seeing the universe in wood grains".
FeaturingDutch-importedSIKKENS water-based paintthat preserves the wood's breathability with plant-based emulsion.
