# Blue Glass 3D Style
A photorealistic 3D render with blue glass material. Objects should have:
- Glossy, translucent blue glass surface
- Subtle reflections and refractions
- Solid black background
- Soft studio lighting from above-left
- Sharp shadows
## Color Palette
- Primary: Deep blue (#1a4b8c)
- Highlights: Light cyan (#7fdbff)
- Background: Pure black (#000000)
## Technical Notes
- Use ray-traced rendering appearance
- Include caustic light effects
- Maintain consistent material across objects
Usage
# Apply style to generation
uv run python main.py out.png "gear icon" --style styles/glass.md
# Combine with reference
uv run python main.py out.png "cube" --style styles/glass.md --ref prev.png
Style vs Reference
| Concept | Type | Purpose |
|---|---|---|
| Style | Text (.md) | Artistic direction via description |
| Reference | Image | Visual example for consistency |
Both can be combined for best results.
Security Notes
Style files are validated for potential injection patterns:
- No bash/shell code blocks
- No variable expansion (${ })
- No command substitution ($( ))
- No shell operators (& | ; `)
Suspicious patterns generate warnings but don't block creation.
Writing Effective Styles
- Be Specific: "Soft watercolor washes with visible paper texture"
- Include Colors: Hex codes ensure consistency
- Describe Mood: "Mysterious, slightly unsettling"
- Technical Details: Lighting, camera angle, rendering style
- Keep It Focused: One style per file

Includes mandatory sub-agent delegation patterns, agent selection guide, file-based instructions, and strict rules to prevent context window pollution.
