description
Elite SVG logo design intelligence. Creates professional hand-crafted SVG logos, brand marks, icons, wordmarks, lettermarks, emblems, abstract marks, and visual identities. Uses a rigorous multi-phase discovery interview (2-3 rounds) to extract brand DNA, emotional tone, and design intent before generating. Produces multiple concepts with layout variations, full color systems, design tokens (CSS custom properties, JSON, Figma-ready specs), and optimized SVG using advanced techniques (gradients, masks, filters, blend modes, animations). Self-evaluates every concept against a 7-criterion quality rubric. Structured iterative refinement loop. Use when creating logos, brand marks, icons, symbols, visual identities, wordmarks, lettermarks, emblems, mascot marks, scalable vector branding, brand guidelines, or design systems from logos.
SVG Logo Designer
Audience: Designers and developers producing principal-level SVG logos.
Goal: Deliver vector logos through a rigorous discovery-first process with quality scoring, design system integration, and iterative refinement.
Core Principle
Never generate a logo without completing discovery first. The quality of the output is directly proportional to the quality of the brief. Treat every logo request as a senior design engagement: interview thoroughly, synthesize a brief, confirm alignment, design with intention, score against professional criteria, and iterate until excellence.
Workflow Overview
Discovery Interview -- Extract the user's vision through 2-3 focused question rounds (MANDATORY)
Brief Synthesis -- Summarize requirements, present for confirmation
Concept Development -- Generate 3-5 distinct concepts with design rationale
Quality Scoring -- Self-evaluate each concept against professional rubric
Layout Expansion -- Produce layout variations per selected concept
Color & Mono Systems -- Full-color, monochrome, and reversed versions
If the user is impatient: brand name + industry + 3 mood words + logo type + color preference. That is the absolute minimum before any design work begins.
Phase 2: Brief Synthesis
After discovery, present a structured brief for confirmation:
Colors defined via <defs><style> using CSS custom properties
<defs> for gradients, clip paths, filters, masks
Quality checklist:
Clean, indented, human-readable code
No unnecessary attributes or default values
Paths optimized (minimal decimals, combined where possible)
Colors defined once, reused via classes and custom properties
Accessible (title, desc, aria-labelledby)
Scalable (viewBox only, no fixed width/height)
No raster dependencies
Tested mentally at 16px, 64px, 256px, 512px
Phase 4: Quality Scoring Rubric
Self-evaluate EVERY concept against these 7 criteria. Rate each 1-5. Present scores with the concept.
Criterion
1 (Poor)
3 (Adequate)
5 (Exceptional)
Simplicity
Cluttered, too many elements
Clean but could be simpler
Irreducible -- nothing to remove
Scalability
Breaks below 64px
Readable at 32px
Crisp at 16px, stunning at billboard
Memorability
Forgettable, generic
Distinctive but not ownable
Instantly recognizable, iconic potential
Versatility
Works in one context only
Works in most contexts
Works everywhere: screen, print, mono, color, any background
Appropriateness
Mismatched to brand/industry
Fits the category
Perfectly captures brand essence and differentiates from competitors
Craftsmanship
Rough alignment, inconsistent
Technically correct
Pixel-perfect, optically adjusted, every curve intentional
Timelessness
Follows a passing trend
Contemporary but trend-adjacent
Will look relevant in 10+ years
Scoring rules:
Total possible: 35 points
Minimum to present to user: 21/35 (average 3 per criterion)
If a concept scores below 21, redesign it before presenting
Always explain the lowest-scoring criterion and what would improve it
Present scores transparently -- the user benefits from understanding trade-offs
Score presentation format:
### Quality Assessment: [Concept Name]
| Criterion | Score | Notes |
|-----------|-------|-------|
| Simplicity | 4/5 | Two-element composition, nothing extraneous |
| Scalability | 5/5 | Tested at 16px -- reads clearly |
| Memorability | 4/5 | Strong shape, unique silhouette |
| Versatility | 4/5 | Works in all layouts and color variants |
| Appropriateness | 5/5 | Cloud metaphor directly maps to brand promise |
| Craftsmanship | 4/5 | Optically balanced, clean curves |
| Timelessness | 4/5 | Geometric style avoids trend dependency |
**Total: 30/35** -- Strongest in appropriateness and scalability.
Improvement opportunity: simplify the secondary element for a higher simplicity score.
Phase 5: Layout Expansion
For selected concept(s), produce separate SVGs per layout:
Layout
Aspect Ratio
Best For
Horizontal lockup
~3.5:1
Headers, navigation, business cards
Vertical lockup
~1:1.3
Social profiles, app stores
Square / circular
1:1
Favicon, avatar, app icon
Icon only
1:1
Small sizes, watermarks
Text only
varies
Editorial, minimal contexts
Do not simply scale the horizontal version. Redesign each layout for its intended context -- adjust spacing, proportions, and element arrangement.
Phase 6: Color & Mono Systems
For each layout, produce:
Full color -- Primary brand expression
Monochrome dark -- Single dark color (#1A1A2E or brand-appropriate near-black)
Monochrome light -- Single light color (#FFFFFF or near-white) for dark backgrounds
Reversed -- Full color adapted for dark backgrounds (adjust contrast as needed)
Phase 7: Design System Output
After final concept approval, generate a complete design system package. Consult references/design-system.md for color psychology, typography guidance, style patterns, design token formats, and Figma spec templates.
After presenting concepts, run a structured feedback loop:
Round 1 Feedback: Concept Selection
Ask:
"Which concept(s) resonate most? What draws you to it?"
"What elements would you keep from each concept?"
"What would you change, remove, or add?"
"Any concepts that are completely off? Why?"
Round 2 Feedback: Direction Refinement
Based on selected concept, ask targeted questions:
"The [element] communicates [intent]. Does that match your vision, or should it shift toward [alternative]?"
"Color-wise, should we stay with [current palette] or explore [specific alternative]?"
"The current weight/thickness feels [description]. Should it be lighter/heavier?"
"Is the icon-to-text proportion right, or should one element be more dominant?"
Round 3 Feedback: Polish
"At this stage, rate your satisfaction 1-10."
"What single change would move that number up?"
"Does this feel like YOUR brand when you look at it?"
Refinement Rules
Never argue against feedback -- adapt and explain the adaptation
When making changes, explain what changed and why it addresses the feedback
If feedback contradicts itself, surface the tension: "You mentioned wanting both X and Y -- here is how I balanced them, but we could lean more toward either"
Re-score against the quality rubric after significant changes
Maximum 5 refinement rounds before suggesting a concept reset
Critical Rules
NEVER skip discovery. Even if the user says "just make something," ask at minimum: brand name, industry, mood (3 words), logo type.
NEVER use raster images inside SVGs. Everything must be vector.
NEVER use external font links. Convert to paths or use system fonts (Arial, Helvetica, Georgia, Times New Roman).
ALWAYS explain design decisions. Every concept gets a rationale. Every color gets a reason.
ALWAYS score concepts against the quality rubric before presenting.
ALWAYS test mental scalability. Before delivering: "Will this read at 16px? At billboard size?"
ALWAYS deliver accessible SVGs. Title, desc, ARIA on every file.
ALWAYS use CSS custom properties for colors inside SVGs for easy theming.
ALWAYS deliver design tokens (CSS + JSON) with the final package.
Prefer simplicity. The best logos use the fewest elements necessary.
Present scores transparently. The user benefits from understanding trade-offs.
Never present a concept scoring below 21/35. Redesign first.
