The rustic style (or rust-inspired style) is a creative design style that simulates the visual effect of metal oxidation and rusting. Its core lies in restoring the color layers, texture, and traces of time of rust to create a retro, industrial, vicissitudes, or rough visual atmosphere. It breaks the delicacy of conventional designs and conveys a unique sense of temporal narrative.

In terms of presentation features, its typical elements include the color gradient of rust (transitioning from the original metal color to orange-red, yellow-brown, dark brown, and even accompanied by local patina spots), mottled peeling textures (such as blocky rust layers, fine rust lines, and blurred-edged rust stains), as well as defective details like scratches and dents on the metal base. In application scenarios, it is not only commonly used in industrial-style brand logos, retro poster designs, and machinery-themed cultural and creative products but also in the aging of props in film and television art, the treatment of metal components in interior decoration. Even in digital design, rust effects are simulated through techniques such as texture overlay and color overlay, which can be applied to fonts, graphics, or product appearances.

This style can not only enhance the retro tone and industrial texture of the design but also trigger associations with the passage of time and retro feelings through the visual symbol of "rust", combining visual impact with emotional resonance.
