局部色彩保留人像AI提示词，橙色外套与黑白拖影

Photograph, selective color technique, a young woman in side profile half-body portrait positioned slightly left of center, facing the right side of the frame, body slightly turned, the only colored subject in the image. She wears a high-saturation orange collared jacket with soft fabric folds and slight sheen, two dark thin shoulder straps hanging down from her shoulders. She has dark wavy short hair blown back by wind, with a clear rim light on the edges. Her facial contours are clear, straight nose, lips slightly parted, gaze directed toward the right distance, calm and slightly detached expression. The background is a black-and-white grayscale strong horizontal motion blur streak, composed of horizontal bands and blurred patches of varying darkness, like a fast-moving crowd or city street stretched into flowing gray ribbons, completely out of focus with no recognizable objects. The figure is positioned slightly left of center, head in the upper third, the orange jacket occupying the middle and lower part of the frame, the closest visual anchor to the camera. Light comes from the front-right side, hard side light illuminating her nose bridge, cheekbone and jacket front, left cheek and hair falling into soft shadow, obvious light ratio. Overall color is a strong contrast between the black-and-white gray background and the single orange jacket, orange extremely saturated, background desaturated, creating strong visual separation. Slight film grain and soft edge transitions, smooth continuous background streaks, face and hair remain sharp and clear, extremely shallow depth of field, figure completely separated from background. The mood is built by the black-and-white flowing background, the still clear profile and the only bright orange, conveying detachment and focus while moving alone through a fast-flowing crowd. High definition details, realistic optical imaging, no outlines no brushstrokes.
