Change ONLY the lipstick color of the woman. Replace the current dark deep burgundy/plum lipstick with a soft, muted, natural nude lipstick shade (subtle, understated, low-saturation, close to natural lip color with a light rosy-beige tone). Keep everything else in the image EXACTLY the same — same face, same facial features, same skin, same hairstyle and hair color, same expression, same pose, same hand position, same white shirt, same background with sheer curtains and window light, same lighting, same composition and framing. Do not alter anything except the lipstick color. Photorealistic, natural result.
