“RED BANNER”是使用 FontVibe AI 创作的血滴字体文字效果。粗体深红字母，表面湿润暗红，长长的血滴末端凝成圆珠，在侧光下孤立于纯黑背景。

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). “RED BANNER” rendered as the sole dominant title against a pure black void, with the font’s inherent letterform design preserved beneath a saturating layer of thick biological fluid. Deep crimson blood coats the letter faces in uneven glossy sheets, grading from active arterial red #CC0000 along fresh rivulets to dense near-black clot #3D0000 in recessed edges and accumulated base pools. Gravity-driven streams descend from lower contours and interior apertures: wide at their source, progressively thinning into elastic connecting filaments, each ending in heavy tear-shaped droplets with sharply visible curved meniscus and surface tension. Several terminal drops remain attached, swollen and reflective, while shorter clotted drips form matte-dark crusted ridges. Directional cold side light skims across convex liquid surfaces, producing narrow wet specular highlights and deep black occlusion beneath each overhang. Subsurface scattering gives the thickest fresh blood a dark internal red transmission at thin edges. Sparse pinhead micro-splatter and a restrained low pool of coagulating blood surround the title without introducing other colors or decorative objects. Photorealistic horror-film practical-effects finish, macro liquid detail, ray-traced reflections, high contrast, pure black negative space.
