从 Coloring Lesson Forge 派生出的线稿 QA 玩法:玩家检查 AI 涂色页是否真的可涂,逐项圈出 closed contours、large regions、low ink、clear labels 和 safe subject,再把 open/busy 线条修成 color ready。

Use this as a reference for Closed Contours, Colorability Check, Coloring Page, Derived Play workflows, prompt structure, visual constraints, and output review.
Create one polished public-gallery concept image titled exactly "Derived Play: Colorability Check". Use case: derived play mechanic / printable QA game / line-art review. Asset type: landscape 16:9 black-and-white printable challenge sheet for a GPT Image 2 gallery. Primary request: Derive a playable review game from Coloring Lesson Forge. Players inspect an AI-generated coloring page and mark whether it is actually colorable: closed contours, large enough regions, clear labels, safe subject, and low ink. This must be a flat printable challenge sheet, not a tabletop game photo, not a dashboard, not a menu, not a map, not a comic strip, and not a 2x3 contact sheet. Composition: left two-thirds shows a simplified fictional coloring page excerpt titled "Seed Path" with four line-art areas: wind fluff, water pod, carry bag, sprout patch. Place five numbered inspection rings on the artwork. Each ring points to a different issue or pass condition: one open contour, one tiny color zone, one heavy ink patch, one unclear label, one clean pass region. Keep the line art original, simple, black ink on warm white paper. Right third shows a vertical game rail with five short steps: "Find", "Circle", "Name", "Repair", "Pass". Under it show a compact scoring ladder with readable labels: "closed", "roomy", "low ink", "label", "safe". Bottom strip shows two repair examples as tiny before/after contour snippets labeled "open" -> "closed" and "busy" -> "simple". Add a final badge "COLOR READY". Visual style: refined printable classroom design exercise, black-and-white line art with a few gray dotted guide marks, crisp typography, generous spacing, clean hierarchy, low-ink aesthetic, professional but playful. The game should clearly show a human evaluation loop for GPT Image 2 outputs: generated coloring pages become inspectable artifacts with concrete QA rules. Safety and originality constraints: fictional classroom material only; no real students, no real teachers, no faces, no real school names, no brands, no logos, no public figures, no politics/elections/parties, no medical/legal claims, no hazardous instructions, no adult or explicit content, no gore, no celebrity likeness, no copyrighted characters, no living-artist style imitation. Do not copy any external prompt, coloring page, article image, product UI, source image, artwork, character, or protected style.
