AI Sprite Generation: Colors and armor variety too limited

[Gumbees]

Problem

The AI-generated sprites lack variety in two key areas:

1. Colors are not dynamic enough

• Sprites tend to all be the same color (currently defaulting to similar shades)
• The AI isn't picking from the full color spectrum despite prompt instructions
• Need more vibrant, varied colors across generated warriors

2. Armor style lacks variety

• All armor looks like classic plate/chainmail
• This is a game that spans all of time - from Stone Age to far future
• Need visual distinction between eras:
  • Primitive: Furs, leather, bone armor
  • Ancient: Bronze, leather straps, cloth wrappings
  • Medieval: Chain mail, plate armor
  • Renaissance: Ornate armor, musketeer style
  • Modern: Military uniforms, tactical gear
  • Sci-Fi: Power armor, energy shields, sleek futuristic suits
  • Fantasy: Robes, magical auras, demonic/angelic aesthetics

Possible Solutions

• Improve the prompt to be more specific about era-appropriate visuals
• Add an "era" field to SpriteDescription that influences rendering
• Create distinct rendering styles for different armor types
• Consider adding visual elements like glowing effects for sci-fi/magic

Files involved

• src/sprites/generator.rs - AI prompt and parsing
• src/sprites/renderer.rs - Visual rendering of sprites
