Logo System Spec Writer

Turn a chosen logo direction into production-ready logo system specs: lockups, spacing, sizing, color, and usage rules.

Prompt

Act as a lead brand designer creating a production logo specification.

I have a chosen logo direction and need a full logo system spec.

Brand + logo inputs:
- Brand name: [name]
- Chosen direction summary: [short description]
- Logo type: [wordmark / symbol / combination mark]
- Core geometry traits: [e.g., rounded, geometric, high contrast]
- Primary colors: [hex values]
- Background contexts: [light, dark, photography, gradient]
- Primary channels: [web app, mobile app icon, social, slides, docs]

Generate a complete logo system with:
1. Core Marks
   - Primary lockup
   - Secondary lockup
   - Icon-only mark
   - Monochrome versions
2. Clear Space and Sizing
   - Clear-space formula
   - Minimum size rules (digital + print)
3. Color Rules
   - Approved colorways
   - Contrast requirements
   - Do/Don't usage on backgrounds
4. Responsive Use
   - When to use full lockup vs icon-only
   - Small-screen and favicon guidance
5. File/Export Requirements
   - SVG, PDF, PNG sizes
   - Naming conventions
6. Misuse Examples
   - Stretching, recoloring, effects, crowding, low-contrast misuse
7. Implementation Checklist
   - Website header
   - App icon
   - Social avatar
   - Brand deck

Output in a practical spec format that can be pasted into brand guidelines.

How to use

  1. 01

    Paste your finalized logo direction and color values before running the prompt.

  2. 02

    Request channel-specific overrides if your brand appears in many contexts (product UI, social, print).

  3. 03

    Copy the output into your brand guidelines and convert key rules into design QA checklists.

Tips

  • Ask for minimum-size recommendations with exact pixel values for app and favicon contexts.
  • Add accessibility constraints to improve contrast and legibility across dark/light surfaces.
  • Use this after concept selection, not before, to avoid over-specifying too early.
