“boo bye!” 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. Render the exact text “boo bye!” prominently, with “boo” above “bye!” and a lively gap between the lines. Pure black background, with no warm colors or decorative clutter. The lettering is saturated deep crimson, grading from arterial red on the freshest raised surfaces to near-black clot in recessed edges and small pools. Give the letters a wet, viscous blood finish: glossy convex surfaces catch a narrow, cold side light, while dark clotted areas remain matte. Heavy blood gathers along the lower edges of the letters and pulls downward in gravity-shaped drips—wide where each stream begins, narrowing into taut connecting strands and rounded teardrop terminals with visible surface tension. Vary the drip lengths, letting a few longer trails hang beneath the words without obscuring their readability. Add subtle near-black pooling at the letter bases and a restrained scattering of tiny dark-red droplets against the void. Keep the composition playful in its compact, bouncing arrangement, but make the material unmistakably eerie and visceral, like practical horror-film blood under dim crimson side lighting.
