Brand Guidelines

Brand Guidelines

How to use the Holiday Lydian name, colours, typography and logo — the real design tokens the platform ships with.

Name usage

The product is "Holiday Lydian". The operating company is "Lydian AI Inc". Write the product name with both words capitalised and never abbreviate it to "Lydian" alone in a way that could be confused with the company. Use the company name in legal, financial and corporate contexts; use the product name for the consumer platform.

Tone of voice

We are clear, honest and helpful. We describe what the platform actually does — never more. We avoid hype, superlatives we cannot back up, and invented metrics. Copy is friendly and direct, respects the traveller's time, and works across 9 languages without idioms that do not translate.

  • Clear over clever — say the useful thing plainly.
  • Honest about capability — no claims we cannot verify.
  • Localisable — write so it reads naturally in every supported language.

Colour palette

Warm Clay (#E97451) is the primary brand colour. The palette below is taken directly from the platform's Tailwind theme — use these exact values.

Logo usage & spacing

Holiday Lydian logo
  • Keep clear space around the logo equal to at least the height of the logo mark.
  • Do not render the logo so small that the mark becomes illegible.
  • Place the logo on backgrounds with sufficient contrast; use the warm-clay mark on dark surfaces.

Do & don't

Do

  • Use the exact colour and font values above.
  • Preserve the logo's aspect ratio and clear space.
  • Describe the platform's real capabilities.

Don't

  • Recolour, stretch, rotate or add effects to the logo.
  • Recreate the wordmark in a different typeface.
  • Imply endorsements or partnerships that do not exist.
