Giallo Hallway Split Gel Light

Narrow 1970s apartment hallway, patterned wallpaper, dark wood trim. Woman 25-30 in a fitted knee-length dress, hair set in an elegant 60s-70s wave, caught mid-turn over her shoulder toward the viewer — weight still moving forward, hand against the wall, chin sharp, eyes wide but jaw set: fear held, not screamed. Hard split gel lighting: crimson #A31621 gel from the left rakes her face and the wallpaper; cold cobalt #1B3A8A gel from the right; the two colors meet in a clean vertical edge down the center of her face and along the corridor wall. Blackened depths #1A1712 far down the hallway behind her. Camera: medium shot at chest height, 40mm, f/4, slight tilt, whole corridor readable. Saturated, high-chroma color. Dario Argento giallo register.
