Change Wall Paint Color

ROLE
Act as a professional architectural photo retoucher and interior visualization specialist. Treat the uploaded room photograph as the ground truth for layout, surfaces, furnishings and perspective.

EDIT
Repaint [TARGET WALLS] in [WALL COLOR]. Change only the selected wall paint and the minimal physically connected color reflections needed to integrate it. Preserve the original room and the existing paint finish.

PRIMARY OBJECTIVE
Create a realistic preview of the same room after repainting the selected walls, without redesigning or furnishing the space.

EDITING PRIORITY
1. Apply the requested color to the correct wall surfaces.
2. Preserve architecture, furnishings and fine boundaries.
3. Retain original lighting, wall texture and surface finish.
4. Keep all untargeted surfaces faithful to the source.

WALL SELECTION & BOUNDARIES
- Follow corners and architectural boundaries to identify each targeted wall plane.
- Preserve ceilings, floors, skirting boards, molding, doors, frames, switches, sockets, vents and fixtures unless they are explicitly part of the selected wall surface.
- Preserve tile, exposed brick, wood paneling and other non-painted materials.
- Keep artwork, mirrors, shelves, furniture and plants in place, with their original details intact.
- Continue the new paint naturally into visible gaps behind furniture and around delicate leaves or decorative objects.
- Preserve visible wall texture, small imperfections and the existing degree of sheen. Do not smooth the wall into a flat digital surface.

LIGHTING & MATERIAL INTEGRATION
- Interpret the requested color as the paint’s base color under neutral illumination.
- Preserve differences between sunlit areas, indirect light, cast shadows and darker corners.
- Retain existing shadow shapes, softness and direction, including shadows cast by frames and furniture.
- Keep highlight detail and natural gradients on textured surfaces.
- Allow only restrained local changes to reflected wall color on immediately adjacent surfaces where physically justified.
- Do not apply a global tint, change white balance, move light sources or alter the time of day.

STRICT PRESERVATION RULES
- Preserve room dimensions, wall angles, ceiling height, openings and camera perspective.
- Do not move, replace, add or remove furniture or decor.
- Keep untargeted walls their original colors.
- Preserve fabric, wood, metal and skin colors outside justified local reflected light.
- Keep the original crop, aspect ratio, focus and photographic character.

ARTIFACT PREVENTION
Avoid paint bleeding onto trim or furniture, halos around objects, erased outlets, inconsistent colors across the same wall plane, flattened shadows, altered architectural lines, invented decor and excessively saturated color casts.

QUALITY CONTROL
Check that the selected walls alone were repainted, all boundaries and fixtures remain intact, the requested hue reads naturally, and the result retains the room’s original depth, lighting and texture.

OUTPUT
Return one edited image only, preserving the original aspect ratio and framing. Do not add paint swatches, labels, captions, watermarks, borders or comparison panels.
