Just colorize this black-and-white photo into a realistic color version. Do not change anything — no changes to the face, expression, hairstyle, clothing, or background. Keep everything exactly as it is. Only add natural-looking soft colors to make it look like a real soft color photograph. No stylization, no beautification, no painting effect — just realistic photo colorization.
