Why This Prompt Exists
Silhouette is the fastest way to identify a character. If all characters have the same silhouette, players can’t tell them apart at a glance.

You get:

  • hero and villain with identical body shapes (no visual distinction)
  • characters that look alike from a distance (confusion in gameplay)
  • no iconic silhouette (character isn’t memorable)
  • silhouettes that don’t match personality (gentle character with sharp angles)
  • unreadable at small scale (avatar, mini-map, UI icons)

But shape language creates distinction:

  • triangle shapes: dynamic, aggressive, villainous (sharp edges, pointed)
  • circle shapes: friendly, soft, approachable (rounded, curved)
  • square shapes: strong, stable, reliable (broad, blocky)
  • rectangle shapes: tall, elegant, noble (vertical, elongated)
  • organic shapes: natural, fluid, unpredictable (asymmetrical, flowing)

Without silhouette design, characters blend together.

This prompt designs distinct character silhouettes.

The Prompt
Assume the role of a character silhouette designer who creates iconic shapes.

Your task is to design distinct silhouettes using shape language.

Generate:

1. SHAPE LANGUAGE CLASSIFICATION

| Shape Type | Emotional Signal | Best For | Silhouette Characteristics |
|------------|------------------|----------|---------------------------|
| Triangle | Aggressive, dynamic, dangerous | Villains, warriors, rogues | Sharp shoulders, pointed elements, angular |
| Circle | Friendly, soft, approachable | Heroes, companions, children | Rounded edges, curved lines, soft volume |
| Square | Strong, stable, reliable | Tanks, guardians, leaders | Broad shoulders, blocky, grounded |
| Rectangle | Tall, elegant, noble | Royalty, elves, ranged characters | Vertical, elongated, slender |
| Organic | Natural, fluid, unpredictable | Nature beings, mages, monsters | Asymmetrical, flowing, irregular |

2. SHAPE VOCABULARY BY CHARACTER ROLE

| Character Role | Primary Shape | Secondary Shape | Silhouette Keywords |
|----------------|---------------|-----------------|---------------------|
| Villain | Triangle | Rectangle | Sharp, angular, pointed, threatening |
| Hero | Circle | Square | Rounded, heroic, approachable |
| Tank | Square | Circle | Broad, blocky, sturdy, protective |
| Rogue | Triangle | Circle | Lean, sharp, agile, quick |
| Mage | Rectangle | Organic | Tall, flowing, mystical, elegant |
| Healer | Circle | Rectangle | Soft, gentle, nurturing, tall |
| Nature being | Organic | Triangle | Asymmetrical, natural, unpredictable |
| Royal | Rectangle | Circle | Tall, elegant, refined, noble |

3. SILHOUETTE ENHANCEMENT ELEMENTS

| Element | Effect on Silhouette | Best For |
|---------|---------------------|----------|
| Cape/cloak | Adds volume, drama | Heroes, villains, royalty |
| Shoulder armor | Broadens silhouette, power | Tanks, warriors |
| Hood | Changes head shape, mystery | Rogues, mages |
| Tall collar | Vertical extension, elegance | Royals, villains |
| Skirt/robe | Volume at bottom, grounded | Mages, healers |
| Wings | Horizontal expansion, dramatic | Angels, demons, flying characters |
| Weapon (drawn) | Extension, threat | Warriors, rogues |
| Pet/companion | Secondary shape | Heroes, nature beings |

4. SILHOUETTE PROMPT TEMPLATE

`[Character role] character silhouette, [primary shape] shape language, [secondary shape] secondary, [silhouette keywords]. [Posture description], [weapon/accessory]. Dark silhouette, white background, readable at small scale. Character design.`

5. READABILITY TEST

| Scale | Minimum Silhouette Requirements |
|-------|--------------------------------|
| 256x256 (avatar) | Distinct head shape, recognizable weapon/accessory |
| 128x128 (mini-map) | Unique overall shape, color helps |
| 64x64 (UI icon) | Extreme simplicity, one distinctive element |
| 32x32 (mobile icon) | Single shape, no small details |

6. CAST SILHOUETTE COMPARISON

When designing multiple characters for the same project, ensure:

- Different heights (short vs. tall)
- Different widths (thin vs. broad)
- Different head shapes
- Different accessory silhouettes
- Different posture tendencies
- Different weapon/equipment placement

7. COMMON SILHOUETTE MISTAKES

| Mistake | Why It's Wrong | Correct Approach |
|---------|----------------|------------------|
| All characters same height | No visual hierarchy | Vary heights by role/importance |
| Similar body shapes | Confusion at distance | Use different shape language |
| Too many small details | Lost at small scale | Simplify, use large shapes |
| No iconic element | Forgetable | Add distinctive silhouette feature |
| Identical stances | Static, boring | Vary postures and poses |

INPUTS:

Character role:
[E.G., "Hero", "Villain", "Tank", "Rogue", "Mage", "Healer"]

Personality:
[E.G., "Aggressive", "Gentle", "Noble", "Mysterious"]

Shape preference:
[TRIANGLE / CIRCLE / SQUARE / RECTANGLE / ORGANIC]

Key equipment:
[E.G., "Sword and shield", "Staff", "Bow", "Claws"]

RULES:
- Triangle = aggressive, dynamic, villainous (sharp edges)
- Circle = friendly, soft, approachable (rounded curves)
- Square = strong, stable, reliable (broad, blocky)
- Rectangle = tall, elegant, noble (vertical, elongated)
- Organic = natural, fluid, unpredictable (asymmetrical)
- Test silhouette at 128x128 pixels before approving
- Characters in the same project must have distinct silhouettes
- Add one iconic silhouette element (cape, hat, weapon, wings)
- Silhouette should communicate personality without details
How To Use It
  • Triangle = aggressive, dynamic, villainous — sharp shoulders, pointed elements.
  • Circle = friendly, soft, approachable — rounded edges, curved lines.
  • Square = strong, stable, reliable — broad shoulders, blocky shapes.
  • Rectangle = tall, elegant, noble — vertical, elongated, slender.
  • Organic = natural, fluid, unpredictable — asymmetrical, flowing.
  • Test silhouette at 128×128 pixels before approving — if it’s not readable, simplify.
  • Characters in the same project must have distinct silhouettes — no two should look alike.
  • Add one iconic silhouette element — cape, hat, weapon, wings, or distinctive accessory.
Example Input

Character role:
“Villain — dark sorcerer”

Personality:
“Calculating, menacing, powerful”

Shape preference:
“TRIANGLE (with rectangle secondary)”

Key equipment:
“Staff with crystal, tattered cloak, tall crown”

Why It Works
Most character designs focus on details (face, costume) before silhouette — resulting in characters that look the same from a distance.

This framework improves outcomes by forcing:

  • shape language classification (triangle, circle, square, rectangle, organic)
  • role-to-shape mapping (which shape for which character type)
  • silhouette enhancement elements (cape, armor, wings, weapons)
  • readability testing (silhouette at different scales)
  • cast comparison (distinct silhouettes across multiple characters)

Failure modes this prevents:

  • Hero and villain with identical body shapes (no visual distinction)
  • Characters that look alike from a distance (confusion, poor UX)
  • No iconic silhouette (character isn’t memorable)
  • Silhouettes that don’t match personality (gentle character with sharp angles)

This improves on: Detail-first character design. Silhouette-first design ensures recognition at any distance.
