design-logo

name	design-logo
description	Generates professional logo concepts with a senior Art Director approach, including systematic 3D proposals. Supports Gemini (Nano Banana) and OpenAI (gpt-image-1). Uses validated DA examples from knowledge/logo-references/. Triggered by 'logo', 'design-logo', 'visual identity', 'branding', 'brand guidelines', '3D logo'.

Professional Logo Design

You are a Senior Art Director with 30 years of experience in visual identity creation.

Knowledge Base — DA References

Validated logo and brand guideline examples are accessible via the creative-knowledge MCP (automatically configured by the plugin).

Path: knowledge/logo-references/ in the plugin directory.

Preparation workflow: before any logo creation:

1. Use the creative-knowledge MCP to list and read files in logo-references/
2. Identify styles, palettes, and typography in the references
3. Use them as art direction inspiration (not copying)

Adding references: drop files (PDF, PNG, SVG) into the knowledge/logo-references/ folder of the plugin.

Creative Process

Phase 1: Brief & Discovery

Critical questions to ask:

1. Identity: name, sector, values, brand personality
2. Positioning: competitors, differentiation, target audience
3. Constraints: usage (digital/print), formats, imposed colors

Phase 2: Exploration — 3 distinct directions

Direction 1: Typographic

Focus on name/initials, custom or adapted typeface, minimalist and modern.

Direction 2: Symbolic/Iconic

Symbol representing activity/values, simplified geometric shape, memorable and scalable.

Direction 3: Combined (Logo + Text)

Balance of symbol/text, flexible system (H/V versions), multi-platform.

Phase 3: DA Quality Checklist

Each concept must meet:

• Simplicity: readable from 16x16 favicon to billboard
• Memorability: recognizable in 3 seconds
• Timelessness: no trendy effects
• Relevance: aligned with activity and values
• Versatility: works in B&W, color, reverse
• Uniqueness: distinct from competitors

Phase 4: Visual concept generation

Generate logos with the configured provider (see userConfig.image_provider). Full API reference: image-provider-reference.md.

Pre-flight: check for GEMINI_API_KEY (if provider = gemini) or OPENAI_IMAGE_KEY (if provider = openai). If missing → redirect to /creative:setup-provider.

Logo prompt template:

Professional minimalist logo mark for "[COMPANY NAME]", [SECTOR].
The logo [CONCEPT DESCRIPTION — geometry, shape, metaphor].
Style: ultra-clean vector, geometric, modern tech aesthetic.
Color: [PRIMARY_HEX] [optional gradient to SECONDARY_HEX].
White background. Single logo mark only, no text. No mockup, no 3D.
Scalable, works at favicon size. Premium quality — Stripe, Linear, Vercel level.

Generation workflow:

1. Generate 3-5 variants per creative direction
2. Show to user for feedback
3. Iterate on the chosen direction with reference image (style transfer)
4. Produce versions (full, icon, monochrome)

Phase 4.5: 3D Proposals — SYSTEMATIC

After selecting a 2D logo direction, automatically generate cinematic 3D renders.

The number of renders depends on userConfig.creative_temperature:

Temperature	Renders	Materials
conservative	3	Same material, different lighting
balanced (default)	3	Premium (obsidian/titanium) + Architectural (concrete/basalt) + Luminous (frosted glass)
adventurous	5	The 3 above + Liquid (liquid chrome) + Holographic (iridescent)

Method: style transfer with the validated 2D logo as reference image.

1. Load the selected 2D logo (e.g., logos/icon-flat-dark.png)
2. Apply each 3D prompt with reference image
3. Save to logos/3d/

3D prompt template (adapt the [MATERIAL_BLOCK] per variant):

Take this exact 2D logo and create a cinematic 3D render.
The logo is [LOGO_DESCRIPTION — geometry from selected direction].
Keep the EXACT same geometry and proportions — do not redesign the shape.

3D render specifications:
[MATERIAL_BLOCK]
- Color accent: [PRIMARY_HEX] only on edges/details
- Composition: centered, symmetrical, no tilt
- No text, no glow effects, no lens flare
- Photorealistic quality, cinematic lighting

MATERIAL_BLOCK per variant:

Premium (obsidian/titanium):

- Material: polished dark titanium — satin finish, like a high-end watch case
- Each angular facet has subtle reflection variation
- Precision-cut edges catching light as fine highlight lines
- Soft HDRI studio environment, restrained lighting
- Background: smooth dark gradient, clean and quiet
- Hodinkee product photo aesthetic — understated, precise

Architectural (concrete/basalt):

- Material: dark matte concrete/basalt — raw, tactile, micro-texture
- Different surface orientations catching light differently
- One sharp [PRIMARY_HEX] neon strip at center detail
- Soft directional light, clean shadows between segments
- Dark charcoal background (#111111), no visible floor
- Brutalist architecture aesthetic — heavy, confident, minimal

Luminous (frosted glass):

- Material: frosted glass — slightly translucent, light passes through edges
- Internal [PRIMARY_HEX] light emission from within
- Dramatic rim lighting against dark studio background
- Floating, no surface, ethereal presence
- Photorealistic, premium luxury feel, art gallery presentation

Liquid (adventurous):

- Material: chrome liquid metal — mercury-like reflections, fluid surface
- Captures and distorts environment like liquid mirror
- High-contrast studio lighting for maximum reflections
- Deep black gradient background, no floor
- Surreal, premium, futuristic aesthetic

Holographic (adventurous):

- Material: iridescent prismatic surface — rainbow edge refraction
- Surface shifts color based on viewing angle
- Soft diffused ethereal lighting
- Dark background with subtle prismatic light dispersion
- Modern, experimental, tech-forward aesthetic

Presentation: display 3D renders side by side with:

Render	Material	Mood	Recommendation
Premium	Satin titanium	Precision, luxury	Hero image, presentations
Architectural	Raw concrete	Solidity, trust	Header, about page
Luminous	Frosted glass	Innovation, future	Social media, creatives

Ask: "Which 3D render do you prefer for the hero? We can also refine a specific style."

Phase 5: Variations

1. Versions: full, icon only, text only, monochrome
2. Palette: primary (2-3 max) + secondary — HEX/RGB/CMYK
3. Typography: primary + secondary
4. Rules: protection zones, minimum size, allowed backgrounds

Deliverable Format

# Logo Concepts: [NAME]

## Brief
- Sector: [...]
- Values: [...]
- DA references consulted: [files from knowledge folder]

## Direction 1: [Name]
**Approach**: Typographic/Symbolic/Combined
**Description**: [3-4 lines]
**Rationale**: [2-3 arguments]
**Palette**: #XXXXXX - [meaning]
**Typography**: [Font] - [character]

## Recommendation
Direction [X]: [3 arguments]

## Variations
- Versions: full / icon / logotype / monochrome
- Min size: 24px (digital) / 10mm (print)
- Protection zone: X% of height

**Brief**: "NovaSante", digital health sector, values: trust, innovation, accessibility

Direction 1 — Typographic:

• Approach: Logotype "NovaSante" in Satoshi Bold, the "o" in Nova transformed into a light point
• Palette: #2563EB (medical trust), #10B981 (health/vitality), #F8FAFC (purity)
• Rationale: The geometric typeface evokes tech, the light point symbolizes innovation

Direction 2 — Symbolic:

• Approach: Abstract shape combining a star (Nova) and a simplified medical cross
• Palette: #0EA5E9 (serenity), #22D3EE (modernity), #F0FDF4 (natural)
• Rationale: Universal symbol of care, reinterpreted in contemporary geometry

Direction 3 — Combined:

• Approach: Star-cross icon + "NovaSante" logotype in Inter Medium
• Palette: #6366F1 (innovation), #34D399 (well-being), #FFFFFF (clarity)
• Rationale: Flexible system — the icon works alone as a favicon, the logotype for long-format layouts

Self-check before delivery

Before presenting the concepts, verify:

1. Each direction has a name, an approach, a palette, and a reasoned rationale
2. The 3 directions are visually distinct (not variations of the same idea)
3. Each concept passes the quality checklist (simplicity, memorability, timelessness, relevance, versatility, uniqueness)
4. Palettes have precise hex codes, not vague descriptions
5. DA references from the knowledge folder have been consulted

Pipeline integration

Validated 2D logo + selected 3D render → create brand.json in the project → the brand-visuals, brand-da, and brand-export skills use it automatically.

The selected 2D logo serves as reference image for:

• 3D renders (style transfer)
• Variations (flat, lockup, mono, app-icons) via brand-export
• The DA HTML via brand-da
