# Cover Design Psychology — Cover Design Psychology Methodology

Specialized knowledge used by the cover-designer agent when designing covers and generating images.

## Why Cover Psychology

**67% of readers pick up a book based on its cover**. In online bookstores, covers are displayed at thumbnail size, so they must stand out even when small. The cover is "the message read before the first sentence."

## Genre-Specific Cover Conventions

### Business/Self-Help

| Element | Convention | Reason |
|---------|-----------|--------|
| **Background** | Solid color or gradient | Clean, professional |
| **Typography** | Large bold title, small subtitle | Title IS the core message |
| **Image** | None or icons/symbols | Concept communication |
| **Color** | Blue, black, white (trust) | Professionalism |
| **Author Name** | Large (celebrity) / Small (debut) | Leveraging authority |

### Fiction (Literary)

| Element | Convention | Reason |
|---------|-----------|--------|
| **Background** | Atmospheric illustration/photo | Hints at the world |
| **Typography** | Genre-appropriate typeface | Genre signaling |
| **Image** | Character silhouettes, symbolic objects | Curiosity trigger |
| **Color** | Varies by genre (see below) | Emotional induction |

### Fiction Genre Color Codes

| Genre | Primary Color | Secondary Color | Mood |
|-------|--------------|----------------|------|
| **Romance** | Pink, Red | Gold, White | Warmth, passion |
| **Thriller/Mystery** | Black, Dark red | White, Silver | Tension, danger |

### Essay

| Element | Convention | Reason |
|---------|-----------|--------|
| **Background** | Soft colors or textures | Personal, emotional |
| **Typography** | Handwritten feel or serif | Humanity, literariness |
| **Image** | Minimal illustration, watercolor | Emotional atmosphere |
| **Color** | Pastel, warm tones | Comfort, intimacy |

## Typography Strategy

### Font Selection Guide

| Font Category | Feel | Suitable Genres |
|--------------|------|----------------|
| **Serif** | Classic, authoritative, literary | Literary fiction, history, academic |
| **Sans-serif** | Modern, clean, direct | Business, self-help, technical |
| **Script** | Emotional, personal, elegant | Essay, romance, poetry |
| **Display** | Unique, bold, genre-specific | Horror, fantasy, children's |
| **Monospace** | Technical, hacker feel | Programming, sci-fi |

### Title Readability Rules

1. **3 words or fewer**: Long titles prevent large font sizes
2. **Hierarchy**: Title > Subtitle > Author name in descending size
3. **Color Contrast**: Background-to-text contrast ratio 4.5:1 or higher
4. **Whitespace**: Sufficient margins around text (breathing room)
5. **Thumbnail Test**: Is the title readable when shrunk to 3cm x 4cm?

## Cover Layout Patterns

### 5 Basic Layouts

| Pattern | Composition | Suitable Genres |
|---------|-------------|-----------------|
| **Big Title** | Large title + solid background | Business, self-help |
| **Image Dominant** | Full-bleed image + overlay title | Fiction, travel, cooking |
| **Split** | Top/bottom or left/right division (image+text) | Non-fiction, essay |
| **Central Focus** | Central object + surrounding whitespace | Minimal, art |
| **Pattern/Texture** | Pattern background + centered title | Essay, poetry, culture |

4. "What feeling does it give you?" -> Verify emotional response
