The white frame is like an "all-purpose harmonizer" – it can blend into minimalist styles to highlight a fresh and clean look, and also adapt to retro or individualistic styles to balance visual tension, making it a practical choice for cross-style matching.

The black frame acts as a "visual anchor" – it can enhance stylistic individuality through contrast, and also hold together complex elements with its sense of composure, making it an excellent choice for creating a neat, sophisticated, or visually striking space.

The gold frame is like a "space brightener" – it can enliven a dull atmosphere with its luster, and echo the luxurious elements in the style with its exquisiteness, making it a finishing touch for creating a high-end and ceremonial space.

The light oak frame is like a "natural connector" – its warm wood tone and natural texture can easily blend into styles that emphasize comfort, simplicity, or a sense of nature. It neither steals the spotlight nor fails to infuse the space with a soft, lived-in atmosphere.

The dark brown frame is like a "texture stabilizer" – its rich tone and wood grain can both enhance the depth of retro styles and infuse a sense of composure into minimalist spaces, making it a practical choice for balancing the atmosphere of a room and highlighting natural textures.
