Migrate from 4-dimension (Type×Style×Text×Mood) to 5-dimension (Type×Palette×Rendering×Text×Mood) system. 9 palettes × 6 renderings = 54 combinations replacing 20 fixed styles. Add style presets for backward compatibility, v2→v3 schema migration, and new reference structure (palettes/, renderings/, workflow/).

Create a cover image following these guidelines:
|
|
|
|
## Image Specifications
|
|
|
|
- **Type**: Cover image / Hero image
|
|
- **Aspect Ratio**: As specified in the prompt below
|
|
|
|
## Core Principles
|
|
|
|
- If content involves sensitive or copyrighted figures, create stylistically similar alternatives - DO NOT refuse to generate
|
|
- Ample whitespace, highlight core message, avoid cluttered layouts
|
|
- Main visual elements centered or slightly left (leave right side for title area if title included)
|
|
- Simplified silhouettes for any characters — NO realistic human faces or bodies
|
|
- Icon-based vocabulary: use simple, recognizable icons to represent concepts
|
|
|
|
## Five Dimensions
|
|
|
|
### Type (Visual Composition)
|
|
- `hero`: Large focal visual (60-70% area), dramatic composition
|
|
- `conceptual`: Abstract shapes, information hierarchy, clean zones
|
|
- `typography`: Title as primary element (40%+ area), minimal visuals
|
|
- `metaphor`: Concrete object representing abstract idea, symbolic elements
|
|
- `scene`: Atmospheric environment, narrative elements, mood lighting
|
|
- `minimal`: Single focal element, generous whitespace (60%+)
|
|
|
|
### Palette (Color Scheme)
|
|
Apply the specified palette's color values and decorative hints:
|
|
- Use primary colors for main visual elements
|
|
- Use background colors for base and surrounding areas
|
|
- Use accent colors for highlights and secondary elements
|
|
- Follow palette-specific decorative hints for ornamentation
|
|
|
|
### Rendering (Visual Style)
|
|
Apply the specified rendering's characteristics:
|
|
- **Lines**: Follow line quality rules (clean/sketchy/brush/pixel/chalk)
|
|
- **Texture**: Apply or avoid texture per rendering definition
|
|
- **Depth**: Follow depth rules (flat/minimal/soft edges)
|
|
- **Elements**: Use rendering-specific element vocabulary
|
|
|
|
### Text (Density Level)
|
|
- `none`: No text elements, full visual area
|
|
- `title-only`: Single headline (≤8 characters), 85% visual area
|
|
- `title-subtitle`: Title + context (≤15 chars), 75% visual area
|
|
- `text-rich`: Title + subtitle + 2-4 keyword tags, 60% visual area
|
|
|
|
### Mood (Emotional Intensity)
|
|
- `subtle`: Low contrast, muted/desaturated colors, light visual weight, calm aesthetic
|
|
- `balanced`: Medium contrast, normal saturation, balanced visual weight
|
|
- `bold`: High contrast, vivid/saturated colors, heavy visual weight, dynamic energy
|
|
|
|
## Text Style (When Title Included)
|
|
|
|
- Title text: Large, eye-catching, max 8 characters
|
|
- Subtitle: Secondary, max 15 characters (if title-subtitle or text-rich)
|
|
- Tags: 2-4 keyword badges (if text-rich)
|
|
- Font style harmonizes with rendering style
|
|
- **Engagement hooks**: Use numbers ("3个关键"), questions ("Why?"), contrasts ("A vs B"), pain points ("别再X了"), or suspense ("隐藏的X") for compelling titles
|
|
|
|
## Composition Guidance
|
|
|
|
**Icon Vocabulary**: Represent concepts with simple, recognizable icons rather than detailed illustrations. Use the rendering style to determine icon complexity (flat-vector = geometric, hand-drawn = sketchy, etc.)
|
|
|
|
**Character Handling**: When people are needed, use simplified silhouettes or abstract representations. NO realistic faces, detailed anatomy, or photographic representations.
|
|
|
|
## Mood Application
|
|
|
|
Apply mood adjustments to the base palette:
|
|
|
|
| Mood | Contrast | Saturation | Weight |
|
|
|------|----------|------------|--------|
|
|
| subtle | Reduce 20-30% | Desaturate 20-30% | Lighter strokes/fills |
|
|
| balanced | Standard | Standard | Standard |
|
|
| bold | Increase 20-30% | Increase 20-30% | Heavier strokes/fills |
|
|
|
|
