Gemini髪色シミュレーション AI - 自分に似合うナチュラル髪色プロンプト
自分の写真にナチュラルな髪色を AI で試着シミュレーション。ヘアカラー予約前に複数色を比較したい人向けの写真加工プロンプト。
Recolor only the hair of the person in the uploaded photo to a new natural shade. Target color: [SPECIFY — e.g., "cool ash brown (#5C4A3F)" or "warm honey blonde (#C9A66B)" or "deep mahogany (#3E2723)" or "soft chestnut (#7A5A48)"]. Keep the person's hairstyle, hair length, hair texture, partline, and the way hair falls exactly as in the source — only the color of each strand changes. Apply realistic salon-grade color characteristics: subtle root-to-tip variation, natural highlights where light hits, and shadow areas darker than highlight areas. Preserve eyebrow color match (subtly adjust eyebrows to harmonize with the new hair). Do not change the person's face, skin tone, eye color, makeup, expression, clothing, or background. Output at the original resolution, photorealistic with sharp strand-level detail. Do not regenerate the hair from scratch — only recolor existing hair pixels.
Gemini外壁塗装シミュレーション AI - 家の外壁色を写真で試着
一戸建ての外壁色と屋根色を AI で塗り替えシミュレーション。窓・植栽・空はそのまま、外観のリフォーム前検討に使える写真加工プロンプト。
Repaint only the exterior wall surfaces of the uploaded house photo with a new color. Target color: [SPECIFY — e.g., "warm beige (#C9B79C)" or "modern charcoal (#3D3D3D)" or "soft sage (#9CA88D)"]. Also optionally recolor the roof: [SPECIFY OR LEAVE AS-IS]. Keep windows, doors, garage doors, eaves, gutters, fences, landscaping (trees, lawn, planters), driveway, sky, and any people/cars exactly as in the source — only the wall siding/stucco/board surfaces change. Maintain the existing sun direction, shadow patterns, and reflected light onto the walls so the new color reads under the photographed lighting condition. Apply realistic exterior-paint or siding texture (slight matte, weathered consistency). Output at the original resolution, photorealistic. Do not regenerate the entire house — only operate on the wall pixels.
Geminiインテリア配色シミュレーション AI - 部屋の全体カラーコーディネート
リビングの壁・カーテン・ラグ・ソファのトーンを統一する AI 配色プロンプト。Spring/Summer/Autumn/Winter 風の調和パレットを瞬時に試せる。
Recolor the uploaded room photo according to a unified interior color palette.

Apply this palette consistently to the walls, soft furnishings (curtains, rugs, throw pillows, blankets), and accent decor — but preserve the structural elements (floor wood, ceiling, fixed cabinetry, doors, windows, light fixtures) exactly as in the source. Match the existing light direction and shadow softness so the new palette reads naturally. Keep all furniture in the same position; only their textile colors change. Output at the original resolution, photorealistic with appropriate matte/textile texture for each surface.

Target color: [SPECIFY HEX OR NAME — e.g., "warm sage green (#A8B89A)" or "moody navy (#2C3E50)" or "soft terracotta (#C97757)"]. Keep furniture, flooring, ceiling, doors, windows, baseboards, light fixtures, art, and all decor exactly as in the source — only the wall planes are recolored. Maintain the existing light direction and shadow softness so the wall color reads correctly under the room's lighting. Apply the new color with realistic matte interior-paint texture, including how natural light bounces off corners and how shadow areas darken naturally. Output at the original resolution, photorealistic. Do not introduce new highlights, do not regenerate the room from scratch — only operate on existing wall pixels.

Keep the existing furniture, flooring, lighting fixtures, decorations, ceiling, doors, and windows exactly as in the source — only the wall planes change. Preserve the room's perspective, shadow direction, and the way light wraps onto the walls so the new pattern looks like it was physically painted/applied in the same lighting condition. Match the wallpaper scale to the room (typical residential pattern repeat). Output at the original resolution, photorealistic with subtle paper or vinyl texture as appropriate. Do not regenerate the room from scratch — only operate on the existing wall pixels and preserve every non-wall element (furniture, floor, ceiling, fixtures) exactly.
