Template Structure

# Style Name

{Overall description of the visual style. Be vivid and specific.
Include mood, atmosphere, key visual characteristics.}

## Color Palette
- Primary: {color} ({hex})
- Secondary: {color} ({hex})
- Background: {color} ({hex})
- Accents: {colors}

## Technical Notes
{Rendering style, lighting, materials, post-processing}

Example: Blue Glass 3D

# 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
