The brush-and-ink structure of traditional flower-and-bird painting constitutes a unique system infused with the wisdom of Eastern aesthetics, offering profound inspiration for modern color design. This study aims to conduct an in-depth analysis of its brush-and-ink language and color concepts, revealing their contemporary value in emotional expression, aesthetic atmosphere, and spatial layering, while constructing a systematic pathway for transforming classical aesthetics into contemporary design practice. The core of this transformation lies in translating its underlying aesthetic principles rather than simply imitating surface forms. By creatively reinterpreting the spirit of brush and ink, this research seeks to endow modern color design with rich Oriental cultural connotations, thereby effectively expanding its theoretical and practical horizons.
