What this skill does

• Uses whole-image context to infer coherent skin, fabric, object, and environment colors.
• Distinguishes documented color references from plausible creative inference.

How to use

Provide grayscale image, known colors or references, desired realism, and disclosure needs.

Colorize a grayscale photo

Colorize this grayscale 1950s-style family photo naturally; preserve faces, grain, contrast, clothing, and background.

Workflow

1. Record known colors and protected monochrome evidence; mark all unsupported colors as inferred.
2. Use gpt-image v1.0, GPT Image 2 Medium, source, original ratio, batchCount: 1.
3. Request restrained context-aware color without sharpening, restoration, face changes, object additions, or modernized styling.
4. Compare geometry, identity, tonal hierarchy, grain, damage, edges, and era plausibility.
5. Reject neon casts, uniform skin, color bleed, changed objects, cleaned damage, or false claims of historical certainty.

When this Skill selects GPT Image 2, use quality: "medium" and imageSize: "2K" by default; change either only when the user explicitly requests another tier.

Every GPT Image 2 call in this Skill defaults to Medium at 2K; use another tier only when the user explicitly requests it.
