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. A premium Halloween party invitation suite — thick black card stock, envelope with blood-red wax seal stamped with a skull crest. Open invitation card showing "TRICK OR TREAT" in gothic blackletter blood letters as the headline, with party details below in small elegant serif type. Flat lay on dark velvet surface with Halloween props: dried flowers, small candles, vintage keys. High-end event stationery product photography.
