Art Style Creator

This skill guides the creation of comprehensive art style definitions for visual projects.

Workflow

Step 1: Vision & Context

Gather project context:

Project type: Game, illustration, animation, UI, branding
Target audience: Age group, cultural context
Vision statement: 2-3 sentences describing the visual direction
Key words: 5-7 words capturing the style essence
Primary influences: Reference styles, artists, or works

Step 2: Color Palette

Define the color system. See color-theory.md for detailed guidance.

Ask for:

Palette type: Monochromatic, analogous, complementary, triadic, etc.
Dominant color (60%): Background, large areas
Secondary color (30%): Supporting elements
Accent color (10%): Highlights, focal points
Mood alignment: Match colors to intended emotion
Forbidden colors: Colors to avoid and why

Step 3: Line Work

Establish line characteristics. See line-and-shape.md for details.

Define:

Outline approach: Full / Partial / None / Color holds
Base weight: Thin / Medium / Thick (with pixel/pt measurement)
Quality: Clean / Sketchy / Geometric / Organic / Calligraphic
Weight variation: Different weights for FG/MG/BG
Line color: Black / Dark local color / Color holds

Step 4: Shape Language

Define shape characteristics. See line-and-shape.md.

Specify:

Dominant shape: Circle (friendly), Square (stable), Triangle (dynamic)
Complexity level: Simple / Moderate / Complex
Edge treatment: Sharp / Rounded / Mixed
Character shapes: Heroes, villains, NPCs
Environment shapes: Architecture, nature, props
Silhouette priority: High / Medium / Low

Step 5: Composition

Set layout rules. See composition-lighting.md.

Define:

Framing system: Rule of thirds / Golden ratio / Center-focused / Dynamic
Symmetry preference: Symmetric / Asymmetric / Varied
Depth approach: FG/MG/BG presence and treatment
Perspective type: 1-point / 2-point / 3-point / Isometric
Visual hierarchy: Primary method (size/contrast/color/position)
Negative space: Minimal / Moderate / Abundant

Step 6: Lighting & Atmosphere

Define lighting style. See composition-lighting.md.

Specify:

Overall brightness: Dark / Dim / Neutral / Bright
Contrast level: Low / Medium / High / Extreme
Shadow rendering: Gradient / Cel-shaded / Hatched / Minimal / None
Primary light direction: Front / Side / Back / Top / Variable
Light hardness: Soft / Medium / Hard
Shadow color: Black / Colored / Complementary
Atmospheric effects: Fog, particles, god rays

Step 7: Texture & Detail

Set detail approach. See texture-mood.md.

Define:

Detail level: Minimal / Low / Medium / High / Photorealistic
Texture rendering: Painted / Photo / Procedural / Flat / Stylized
Detail distribution: High detail for focus, low for background
Surface treatments: How to handle different materials
Aging/weathering: None / Subtle / Visible / Heavy
Noise/grain: None / Subtle / Visible

Step 8: Mood & Tone

Establish emotional baseline. See texture-mood.md.

Specify:

Core emotion: Joy, sadness, fear, tension, peace, mystery, etc.
Intensity: Subtle / Moderate / Strong
Tone position: Light ↔ Dark spectrum
Energy level: Calm / Moderate / Energetic
Genre alignment: Fantasy, sci-fi, horror, noir, etc.
Elements to avoid: What would break the mood

Step 9: Technical Specs

Document technical requirements. See technical-specs.md.

Define:

Working resolution: Dimensions at DPI
Export resolution: Final output specs
Color mode: RGB / CMYK / Indexed
File formats: Working and export formats
Asset sizes: Characters, environments, UI elements, icons

Step 10: Generate Style Document

Output the complete art style definition using the template below.

Prompt

I'm developing a sci-fi farming simulation game called 'Neon Harvest' and need a complete art style guide to keep our visual team aligned. Please generate a formal style definition document. It should include an overview section with a vision statement and key terms, a color palette breakdown (dominant, secondary, and accent colors with hex codes and usage rules), line work and shape language guidelines, composition and lighting instructions, detail levels and texturing rules, emotional mood settings, technical asset specs, reference influences, and a list of do's and don'ts for our artists.

Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
