The black-and-white decoration style centers on the two colors of black and white, creating a simple yet tension-filled space through light-dark contrast and lines. Black, symbolizing calmness and mystery, is often used for floors, furniture frames, or partial decorations; white, representing purity and transparency, is mostly applied to walls and ceilings to enhance the brightness of the space.

This style emphasizes neat lines, either using geometric shapes to highlight a modern feel or incorporating retro elements (such as black-and-white tiles) to create a classic atmosphere. The sense of hierarchy can be enriched through material differences (like matte black and glossy white, wood and metal), and a small amount of gray can be added to neutralize visual impact. It is suitable for minimalist styles and can also be integrated into industrial, Nordic and other genres, presenting a high-end yet warm texture.
