“77” es un efecto de texto Letras de Sangre creado con FontVibe IA. Letras carmesí gruesas con una superficie roja oscura y húmeda y largos goteos de sangre que terminan en gotas redondas, aisladas sobre negro puro con luz lateral.

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the viscous blood fluid physics, the suspended drips and the pooling. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as viscous crimson blood letters with tear-shaped drops held by surface tension, thinning connecting streams and near-black pooling. COLOR PRIORITY: keep the font's own colors if specified; otherwise arterial red (#CC0000) grading to near-black clot (#3D0000). Square composition, with “77” enormous and centered, the two numerals close enough to read as one forceful title while retaining a narrow black channel between them. Pure black background, empty and unadorned. Give the numerals a dense, wet coating of deep crimson blood, grading from arterial red on raised, freshly flowing surfaces to near-black clot in the recessed shadows and pooled areas. Heavy drips pull downward from the lower edges: broad where they leave the numerals, narrowing into rounded teardrop terminals, with visible surface tension and a few suspended drops. Let a small amount of thick blood collect directly beneath the numerals without obscuring their shape. Cold, dim red side light from the left catches glossy convex surfaces and leaves the opposite edges in near-black shadow; faint subsurface red glow shows through the thickest active drips. Keep the atmosphere stark, visceral, and cinematic. No warm colors, extra lettering, decoration, or watery splashes.
