A square competition-number panel design showing the number "10" only, with no other text. The two digits stand perfectly upright with no lean, each about as wide as it is tall, filling about 75% of the frame width and centred. Strokes are very thick and even, and the counters are wide and open. Each digit is white glossy cut vinyl with a thick, even black vinyl band running round the outside of the glyph at one constant width, entirely outside the white shape and never a thin line inside it. The knife-cut edge of the black band is visible all the way round and lifts very slightly at the outer corners. A fine line of light catches its upper side, and a hairline shadow falls on the panel below. The vinyl is glossier than the panel beneath it, with crisp edges you could pick up with a fingernail. The panel behind is deep racing red satin paint with a subtle fine orange-peel texture, so white, black and red read as three clearly separate tones. A single hard overhead spotlight, cold white, lays a sharp specular axis along the top plane of each stroke and drops deep carbon-black shadow beneath. The panel fades at the edges into a pure black night-circuit darkness. Fine horizontal white speed streaks trail from the left side of the digits, sharp near the glyph edges and dissolving into darkness, with faint motion haze in the air. A thin championship-gold pinstripe runs along the bottom of the panel. The mood is aggressive and high-velocity, like a race car door number under pit-lane light.
