Copy the idea

Take the style with you as a brief for a person, as instructions for an AI assistant, or as design tokens. It describes the idea and the rules — never the example's code.

The recipe

Classic corporate — style recipe: the same text the brief copies.

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
