Colorize this vintage black-and-white / sepia studio portrait of a young woman naturally and realistically. Keep EVERYTHING exactly the same — do not change the composition, facial features, expression, hairstyle, pose, clothing pattern, background or lighting. Only add realistic, natural color: warm healthy skin tones with subtle blush, natural lip color, brown eyes, natural brown hair with soft highlights, and tasteful color on her patterned floral blouse (keep the same pattern and fabric). Neutral softly-lit studio backdrop in muted warm tones. Preserve the original 1950s photographic texture, grain, soft focus and portrait feel. High-detail, photorealistic, historically accurate color grading. Aspect ratio 3:2.
