局部改色与材质调整

Upload a photograph containing the item you want to recolor. Identify that item precisely and name its desired color, material, and surface finish. Create one edited photograph with this single surface change. Treat the uploaded image as the reference for the item's silhouette, proportions, orientation, and position, as well as the surrounding scene. Translate the existing light into believable highlights and reflections for the requested finish; a matte coating should diffuse highlights without flattening the shape. Preserve visible seams, rims, handles, and any existing markings unless the request explicitly includes them in the change. Keep faces, hands, neighboring objects, background textures, crop, and depth of field visually consistent. Do not relocate the item or recolor similar objects nearby. Preserve the contact shadow and avoid color spill onto surrounding surfaces. User request: Change only the small blue planter beside the keyboard in my uploaded desk photo to warm terracotta with a matte finish, keeping its shape and the plant unchanged.
