Brand Guidelines

Brand Guidelines

Before you start

Gather the following from the user. If anything is missing, ask before proceeding:

1. What is the brand? (Company name, product name, or sub-brand)
2. Does a brand exist already? (Existing assets, logos, colors, or greenfield)
3. Who is the target audience? (Demographics, psychographics, B2B vs. B2C)
4. What are the brand values? (3-5 core values the brand should communicate)
5. Who will use these guidelines? (Internal team, agencies, partners, community)
6. What touchpoints must be covered? (Web, mobile, print, social, email, packaging)

If the user only provides a logo and says "write guidelines around this," push back: guidelines without defined brand values and audience produce rules without rationale.

Brand guidelines template

1. Brand Foundation

Brand Mission:     [One sentence — what the brand exists to do]
Brand Values:      [3-5 values with one-line descriptions]
Brand Personality: [3-5 adjectives that describe how the brand feels]
Positioning:       [One sentence — how the brand differs from alternatives]

Place the brand on each personality axis:

| Axis       | Left End      | Position   | Right End     |
|------------|---------------|------------|---------------|
| Tone       | Formal        | [  X  ]    | Casual        |
| Energy     | Calm          | [    X]    | Energetic     |
| Approach   | Traditional   | [X    ]    | Innovative    |
| Warmth     | Professional  | [  X  ]    | Friendly      |

2. Logo Usage

Define the logo system: primary logo, logo mark (icon only), wordmark (text only). Specify minimum size, clear space (defined by a unit like "height of the letter X"), and approved variations (full color, single color, reversed, monochrome).

Document what is not allowed: do not rotate, skew, recolor, add effects, place on busy backgrounds, or recreate the logo. Use provided files only.

3. Color Palette

| Color Name   | Role       | HEX     | RGB           | Usage                           |
|--------------|------------|---------|---------------|---------------------------------|
| Brand Blue   | Primary    | #1A56DB | 26, 86, 219   | CTAs, headings, key UI elements |
| Brand Navy   | Primary    | #0B1F45 | 11, 31, 69    | Backgrounds, text               |
| Neutral 900  | Neutral    | #111827 | 17, 24, 39    | Body text                       |
| Neutral 100  | Neutral    | #F3F4F6 | 243, 244, 246 | Backgrounds                     |
| Success Green| Functional | #059669 | 5, 150, 105   | Success states only             |
| Error Red    | Functional | #DC2626 | 220, 38, 38   | Error states only               |

Rules: primary colors dominate (60-70%), secondary accent (20-30%), functional colors reserved for UI states only. All text-on-background combinations must meet WCAG 2.1 AA contrast ratios (4.5:1 body, 3:1 large text).

4. Typography

| Use Case     | Typeface | Weight     | Size Range | Line Height |
|--------------|----------|------------|------------|-------------|
| H1 headings  | Inter    | Bold (700) | 36-48px    | 1.1         |
| H2 headings  | Inter    | Semibold   | 28-32px    | 1.2         |
| Body text    | Inter    | Regular    | 16-18px    | 1.5         |
| Code         | JetBrains Mono | Regular | 14-16px | 1.6         |

Specify fallback font stacks. Define hierarchy rules: never skip heading levels, maintain consistent spacing.

5. Voice and Tone

Voice is constant; tone adjusts by context.

Voice (always):
- Clear over clever — say what we mean without jargon
- Confident but not arrogant — know our strengths without belittling alternatives
- Helpful first — every communication leaves the reader better informed

Tone by context:
| Context         | Tone                          | Example                           |
|-----------------|-------------------------------|-----------------------------------|
| Marketing       | Energetic, aspirational       | "Ship faster with confidence"     |
| Error message   | Calm, helpful, blame-free     | "Something went wrong. Try again."|
| Documentation   | Precise, neutral              | "Run the following command to..."  |
| Crisis comms    | Direct, empathetic, factual   | "Here is what happened and..."    |

Include a "We say / We don't say" table with 4-6 concrete examples.

6. Application Rules

Show how elements combine across touchpoints: website header, email signature, social avatar, presentations, print. Specify which logo variant, colors, and typography apply to each.

Quality checklist

Before delivering brand guidelines, verify:

• [ ] Brand values and personality are defined before visual rules
• [ ] Logo usage includes minimum size, clear space, approved variations, and don'ts
• [ ] Color palette includes exact values (HEX, RGB) and usage rules
• [ ] All text/background combinations meet WCAG 2.1 AA contrast ratios
• [ ] Typography specifies typeface, weights, sizes, and fallback stacks
• [ ] Voice is defined as constants and tone adjusts by context with examples
• [ ] Guidelines are usable by someone outside the core team without additional context

Common mistakes

• Rules without rationale. "Use Brand Blue for CTAs" is a rule. "Use Brand Blue for CTAs because it provides the highest contrast" is a guideline. Explain why.
• Colors without exact values. "Our blue" means different things on every screen. Provide HEX, RGB, and HSL.
• Ignoring dark mode and accessibility. If your product has dark mode, guidelines must cover both themes.
• Voice guidelines as personality traits. "We are innovative" tells a writer nothing. Show before/after copy examples.
• Static PDF nobody updates. Brand guidelines in a PDF from 2019 are not followed. Make them accessible and maintained.
• No don'ts. Guidelines that only show correct usage leave room for creative misinterpretation.
