Design an original mural for the double doors of an automotive engine paint booth. The concept is “the flow of paint” represented as large abstract ribbons and geometric waves crossing both doors. No spray gun, no mechanic, no visible car, no piston, no text. The flowing shapes should evoke atomized paint and airflow without being literal. Hidden inside the composition, use negative space to subtly reveal simplified engine parts such as cylinder bores, cooling fins or crankshaft shapes. Everything must be made with solid flat colors only, no gradients, no textures and no realistic effects. The design should feel modern, artistic and industrial, similar to contemporary architectural murals or high-end motorsport liveries. Use only black, charcoal grey, light grey and one bold accent color. Clean vector style, large geometric surfaces, easy to paint with masking tape and crisp edges. Mehr sehen
