Recolour this black and white photo into a natural realistic color photo. Keep the original face, identity, pose, clothing, background, lighting direction, and photo composition unchanged. Add historically believable and natural colors to the skin tone, hair, eyes, clothes, and background. Preserve the original photo texture, film grain, shadows, facial details, and vintage atmosphere. Make the result look like a real color photograph, not a modern filter or over-saturated edit. Use soft natural colors, realistic skin tones, subtle fabric colors, and balanced background tones. Do not change the person’s facial features, age, expression, hairstyle, body shape, or scene details. No text, no watermark, no extra objects, no cartoon effect.
