Prompt: “Using the uploaded portrait, create a realistic personal color analysis comparison. Keep the person’s face, expression, hairstyle, pose, and background unchanged. Show four clean side-by-side versions with different shirt colors: warm terracotta, soft sage, cool berry, and crisp navy. Use consistent natural lighting and accurate fabric color. Make the comparison polished and easy to read, with small unobtrusive color labels and no beauty retouching.”
