a bold duotone piece — graphic, punchy and print-like. SURFACE / STYLE: the lettering is rendered in a striking two-color treatment — one bright color dominating the letter face, a second deep contrasting color filling the drop shadow, bevel inset or offset layer — with a visible halftone screen-dot pattern in the dominant color and a crisp hard-edged graphic finish. SCENE ATMOSPHERE: a flat bold poster setting — clean two-tone ground, simple geometric or halftone accents, high-contrast graphic energy. PALETTE: any high-contrast two-color pair — vermillion red + midnight navy, electric blue + hot pink, black + bright accent — flat, saturated and bold, never gradient-soft or muddy. LETTERFORM PRIORITY: when the chosen font carries its own treatment (retro or Clarendon slab, condensed or geo sans, halftone comic, 3D shadow, sticker outline), that font's letterform takes priority and owns the letters; this style governs the two-color split, the halftone dots and the graphic poster finish. FALLBACK MATERIAL: if the font carries no material of its own, render the letters in a bold duotone — bright face with a deep contrasting offset shadow and a halftone dot pattern — so the punchy two-color graphic always reads. A square duotone number mark built around “104”, centered and oversized, occupying nearly three quarters of the frame with strong, clean negative space around it. The numeral faces are vivid vermillion red, packed with a clearly visible, evenly spaced halftone screen-dot texture that becomes denser toward interior counters and lower edges. A thick midnight-navy offset layer pushes diagonally down-right from every numeral, creating a crisp dimensional print shadow with hard stepped corners and no soft blur. Set on a flat warm-cream ground divided by a bold navy semicircle behind the numbers, with sparse vermillion dot clusters radiating outward like celebratory confetti. The composition feels like a punchy edition number for a modern graphic poster: saturated, exact, energetic, and tactile like fresh screen ink on uncoated paper. Keep all edges sharply cut, colors strictly limited to vermillion red and midnight navy with the cream paper field, no gradients, no objects, no devices, no extra words.
