App Conventions: Buttons, the Grid, and Runs
Every stage of Coloring Book Engine follows the same three conventions. Learn them once and every screen in the app reads instantly.
1. Button Color Tells You What Costs Credits
Section titled “1. Button Color Tells You What Costs Credits”- Orange buttons spend AI credits — image generation, AI edits, matter and cover generation. If a button is orange, pressing it calls your AI provider.
- Blue buttons are free — they run locally on your machine (processing, vectorizing, exporting, rendering).
You never have to wonder whether an action will bill you: the color answers before you click.
🟠 Spends AI credits
🔵 Free — runs on your PC
2. The Grid Is Your Book
Section titled “2. The Grid Is Your Book”Every stage is built around the same grid, where each grid item is one coloring page of your book — page 001 is the same page in Sketch, Coloring, Assets, and Videos. Clicking an item opens whatever that stage needs for that page: an editor (masking touch-up, segment coloring) or a viewer (paths, compiled previews, videos).

The grid is also your progress display — each card shows its state (empty, queued, generating, done, error) so a glance tells you where the stage stands.
3. Three Ways to Run Work
Section titled “3. Three Ways to Run Work”Every generation stage offers the same three actions — pick whichever the situation calls for:
- Single item — click one empty card to produce just that page.
- Retry — regenerate or reprocess one card that failed or came out wrong.
- Batch — Run Rest fills only the empty slots (your default; it never re-bills finished pages), while Run All redoes everything (it warns first, and backs up existing work).

Progressing through a stage is just combining these: batch to fill, single/retry to fix, and move on.
Next: Plan — where your book takes shape.
