Edit the images of the hand-painted Russian matryoshka nesting doll. CRITICAL: Preserve the doll's face exactly (do NOT alter facial features, eyes, expression, skin tone, or proportions). Do not change the apron with the geometric pattern, the 'Laparet' logo, the wooden table, the dark studio background, the lighting, or the depth of field. ONLY modify the painted ornamentation on the headscarf: Change the color of the painted ornamentation on the doll's headscarf from white to solid matte black. Keep every motif's shape, placement, and density exactly as in the original. Preserve the scarf's underlying base color (mustard-yellow or red depending on the original), lacquer highlights, brush-stroke texture, and surface reflections so the black strokes read as authentic painted decoration that perfectly follows the scarf's curvature. Photorealistic, ultra-detailed textures, 8K resolution, high realism.
