Write a logo-only design brief: job of the mark, concepts to explore, usage, and don'ts. Not a full brand identity system.
Act as a design director writing a brief for a logo (the mark), not a full brand identity, UI kit, or campaign. The designer should know what to draw, where it must work, and what to refuse.
Inputs:
- Company / product: [Name]
- What they actually do: [Job]
- Audience: [Audience]
- Competitors' marks I can describe: [Competitors]
- Personality (3 adjectives max): [Personality]
- Mandatory: [Mandatory]
- Forbidden: [Forbidden]
- Where it must work: [Applications]
- Color constraints: [Color]
- Deliverables expected: [Deliverables]
- What already exists: [Existing]
Generate:
1. Job of the mark: 5 lines. What it must do at 16px and on a stitch. What it must not do (tell the whole product story).
2. Positioning vs Competitors: how this mark should not be confused with the described marks. No invented competitor logos.
3. Concept territories (4): each with a metaphor, what to explore, what would make it generic. One territory marked "do not bother."
4. Usage matrix: Applications as rows: min size, one-color, reverse, with wordmark vs icon-only. Note failure cases (busy photo, embroidered cap).
5. Color: from Color constraints only. If none, recommend 1 primary + 1 neutral and say it is a recommendation, not a palette system. This brief is not a brand book.
6. Don'ts: 10. Include Forbidden plus cliches (swoosh, abstract letters that look like a chat bubble unless Job is chat, AI sparkle, gradient orb).
7. Designer checklist: 12 yes/no items for the first review (favicon test, photocopy, 1-color, 3 strangers naming the category).
8. Out of scope: explicitly not typography system, not illustration library, not UI components. Point to a later brand book if needed.
Constraints:
- Do not write a full identity (type scale, photography, voice). Logo only.
- Do not invent trademarks or "this looks like Nike."
- Honor Mandatory and Forbidden.
- No "make it pop." No fake awards.
- If Existing is a logo they must evolve, say what to keep (geometry, name spelling) vs dump.
