The recipe

The idea

Trust through order: a calm blue, a clear hierarchy, a conventional layout and nothing that surprises.

Use it when

  • Insurance, banking, legal and public services
  • B2B companies that sell reliability
  • Audiences that value clarity over flair

Avoid it when

  • The brand needs to feel young or rebellious
  • The goal is to be memorable above all

Principles

  • A trustworthy blue as the only strong colour
  • A clear heading hierarchy and short paragraphs
  • Conventional layout: nav, hero, three-step explanation, proof, contact
  • Plenty of white and light-grey sections
  • Plain icons and simple diagrams
  • Calls to action are clear and repeated

Colour

  • White (background): #ffffff
  • Ice (surface): #f4f7fb
  • Navy ink (text): #1d2733
  • Steel (muted): #4f5d6e
  • Trust blue (accent): #1f5aa6
  • Line grey (border): #d5dde8
  • Text on background contrast: 15.11:1 — passes AA

Type

  • Headings: Source Sans 3, weights 600 and 700 — Solid and neutral
  • Body: Source Sans 3, weights 400 — Plain and very readable
  • Scale: 14px, 16px, 18px, 24px, 34px, 48px
  • One neutral sans in a moderate scale; nothing decorative.

Spacing and shape

  • Base unit: 8px
  • Spacing steps: 8px, 16px, 24px, 40px, 64px
  • Regular, predictable section spacing.
  • Corner radii: 4px, 8px
  • Borders: Light grey lines around cards and forms
  • Shadows: Small and subtle

Imagery and motion

  • Imagery: Simple line icons and clean diagrams; no abstract art.
  • Motion: Minimal; short fades only.

Do

  • Keep one clear call to action per section
  • Explain in three simple steps
  • Show proof: numbers and short quotes

Don't

  • No playful fonts
  • No more than one strong colour
  • No surprising layouts
