Solid Color Background

ROLE
Act as a senior professional photo retoucher, image editor, photographer and AI image-editing specialist. Perform a controlled, production-quality edit of the uploaded image. Treat the source image as the ground truth: preserve everything that is not explicitly requested to change.

EDIT
Replace only the existing background with a clean, uniform [TARGET COLOR] solid-color background. Preserve the foreground subject exactly, including identity, pose, clothing, hair, accessories, proportions, lighting and all fine boundary details. Do not redesign, relight or regenerate the subject.

PRIMARY OBJECTIVE
Execute the requested "Solid Color Background" edit convincingly and cleanly. The finished image should have a visually uniform solid [TARGET COLOR] background with professional subject extraction, accurate edges and no remnants of the original environment or obvious AI-generation artifacts.

EDITING PRIORITY
1. Replace the existing background completely with the requested solid color.
2. Preserve the foreground subject and identity exactly.
3. Protect difficult boundaries such as hair, eyelashes, glasses, fingers, clothing and transparent or semi-transparent details.
4. Maintain clean, natural subject edges without halos, cutout artifacts or color contamination.
5. Preserve the original photograph everywhere except the background.

BACKGROUND REPLACEMENT — IMPORTANT
- Replace the entire existing background with [TARGET COLOR].
- The replacement background should appear as one clean, visually uniform solid color.
- Do not retain recognizable objects, structures, scenery, textures or patterns from the original background.
- Do not introduce gradients, patterns, textures, decorations, scenery or additional objects.
- Do not add walls, floors, studio equipment, furniture, windows or environmental features.
- Do not add artificial background blur or depth-of-field texture.
- Do not create visible seams, bands, patches or inconsistent areas within the solid background.
- Maintain consistent color across the entire replacement area.
- If a specific HEX, RGB or named color is provided, reproduce it as closely as practical.
- Do not unnecessarily shift the requested color because of the source scene's original background coloration.

SUBJECT EXTRACTION & EDGE INTEGRITY
- Preserve the foreground subject exactly.
- Protect individual hair strands and fine flyaway hairs where visible.
- Preserve eyelashes, eyebrows, ears, fingers and other fine anatomical boundaries.
- Preserve clothing edges, fabric fibers, lace, fringe and other delicate garment details.
- Preserve glasses frames and realistically handle transparent or translucent lenses.
- Preserve jewelry, accessories, straps and other small foreground details.
- Maintain natural anti-aliased edges appropriate to the source image resolution.
- Do not create unnaturally hard cutout edges.
- Do not excessively soften or blur subject boundaries.
- Do not remove genuine fine hairs simply to create a cleaner mask.
- Do not leave fragments of the original background between hair strands or around difficult boundaries.
- Avoid bright or dark halos around the subject.

COLOR SPILL & CONTAMINATION
- Remove unwanted color contamination from the original background only where it appears directly on boundary pixels because of background spill.
- Preserve genuine lighting and reflected color that belongs naturally to the subject.
- Do not globally recolor the subject to match the new background.
- Do not allow the target background color to bleed onto skin, hair, clothing or accessories.
- Preserve natural skin tones and original clothing colors.
- Distinguish genuine environmental lighting from removable background-edge contamination conservatively.

SUBJECT PRESERVATION
- Preserve the subject's recognizable identity exactly.
- Preserve facial geometry, expression, eye appearance, hairstyle and hairline.
- Preserve body shape, proportions, anatomy and pose.
- Preserve skin texture, pores, freckles, moles, scars, tattoos and other distinguishing features.
- Preserve clothing design, material, color, fit, patterns, logos and text.
- Preserve jewelry, glasses and accessories.
- Do not apply beauty retouching, skin smoothing, facial enhancement or body reshaping.
- Do not change hairstyle, makeup, grooming or expression.
- Do not alter the subject merely to simplify background removal.

LIGHTING PRESERVATION
- Preserve the original lighting on the subject.
- Preserve existing highlights, shadows, contrast and color temperature.
- Do not introduce a new key light, rim light or studio-lighting setup unless explicitly requested.
- Do not artificially illuminate the subject using the new background color.
- Preserve natural dimensionality and existing light falloff across the subject.
- Do not flatten the subject's lighting simply because the background is now uniform.

STRICT PRESERVATION RULES
- Do not change anything except the existing background unless a tiny boundary correction is absolutely necessary for realistic extraction.
- Preserve the original composition, crop, camera position, perspective and aspect ratio.
- Preserve all foreground people and objects unless explicitly instructed otherwise.
- Preserve facial identity, body proportions, pose, hand position and anatomy.
- Preserve clothing, accessories, jewelry, tattoos, scars, freckles, moles, logos and other distinctive details.
- Preserve realistic texture in skin, hair, fabric, metal, glass and other foreground materials.
- Do not introduce unrelated props, people, text, logos or decorations.

REALISM & INTEGRATION
- Match the original camera perspective, lens characteristics, focus and depth of field on the foreground subject.
- Preserve the source image's grain, noise structure, sharpness and compression character.
- Ensure subject edges retain an appropriate level of sharpness for their original focal plane.
- Maintain realistic transparency and partial transparency around hair, glasses and other relevant boundaries.
- Prevent masking artifacts from making the subject appear pasted onto the new background.
- Preserve subtle edge softness caused by the original lens and focus.
- Keep the final composite technically clean at both normal viewing size and close inspection.

ANATOMY & GEOMETRY SAFETY
- Keep human anatomy physically correct.
- Preserve the correct number and structure of fingers, hands, arms, legs, eyes, ears and teeth.
- Do not warp facial features, limbs, clothing or accessories during background replacement.
- Do not crop away or regenerate body parts.
- Do not create duplicate features or objects.
- Preserve the subject's original scale and placement within the frame.

ARTIFACT PREVENTION
Avoid:
- remnants of the original background
- accidental gradients
- background texture
- banding or patchy color
- inconsistent solid-color regions
- halos around the subject
- jagged masking edges
- excessively hard cutout edges
- excessive edge blur
- missing hair strands
- background fragments trapped between hair
- target-color spill onto the subject
- altered skin tones
- transparent or missing clothing edges
- damaged glasses
- distorted fingers or anatomy
- changed facial identity
- altered clothing
- artificial relighting
- unnecessary subject regeneration
- obvious generative-AI artifacts

QUALITY CONTROL
Before finalizing, inspect the entire image and mentally compare it with the source. Verify that:
- the original background has been completely replaced;
- the new background is a clean and visually uniform [TARGET COLOR];
- no original scenery, objects or textures remain;
- no unintended gradients, patterns or background variations were introduced;
- the foreground subject remains faithful to the source;
- facial identity, expression, body shape and pose remain unchanged;
- hair strands and other fine boundaries remain natural;
- glasses, jewelry, clothing and accessories remain intact;
- no halos, jagged edges or background contamination are visible;
- skin tone and clothing colors remain faithful to the original;
- the subject's original lighting remains preserved;
- no unintended edits were made outside the background;
- the result remains technically clean at close inspection.

OUTPUT
Return one polished final image only. Preserve the original aspect ratio and framing unless the requested edit explicitly requires otherwise. Use the highest practical image quality and detail available. Do not add captions, watermarks, borders or explanatory text to the image.
