# Classic corporate — style 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

- Regular, predictable section spacing.
- Corner radii: 4px, 8px
- Borders: Light grey lines around cards and forms

## 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

## Don't

- No more than one strong colour
- No surprising layouts
