A racing car number livery design: the two glyphs "7号" on a pure black night-circuit background, one large numeral "7" with the Chinese character "号" beside it. The 7 is dominant and fills about 70% of the canvas width. 号 is set at about 45% of the height of the 7, aligned to the baseline at its lower right, in the same slanted style. Render exactly these two glyphs and nothing else. Letterform: wide, low display lettering, plainly wider than tall, with an aggressive forward lean so every top sits far to the right of its foot. Every stroke ends in the same razor-sharp slanted cut, all parallel, each long enough to read as a main edge of the glyph. Every inside corner is turned in one wide smooth curve. The 7 has a thick horizontal bar and a heavy diagonal stem. 号 is simplified into thick, even strokes with generous counters, so it stays legible on a car door. Every glyph is a closed solid shape, with clear gaps between glyphs. Material: formed sheet metal under high-gloss automotive paint. Each face is one flat plane in saturated racing red, with an even gloss and no reflected detail. A narrow chamfer runs around the whole edge. A hard, unbroken white highlight line runs along the top chamfer across the full width of the glyphs, and the lower chamfer goes carbon-black. A thin championship-gold outline band sits just outside the glyph edge. A soft red halo hugs the glyphs closely. Light and stage: a single hard overhead beam, cold white, slightly from the front. A deep carbon shadow falls behind and to the right of the glyphs, in the direction of motion. Fine pure-white horizontal speed lines trail behind each stroke on the left. They are sharp at the glyph edge and fade into the darkness. A faint motion haze hangs in the air, with a distant track-light flare at the upper right. A dark asphalt strip with one faint white painted line fills the bottom 12% of the frame. Palette: racing red, championship gold, carbon black, pure white. Centered composition with tight margins. Flat, front-on view, crisp edges, a clean production-ready number design for a livery.
