Paper, gold leaf, a garden at golden hour.

Build The Day feels like an invitation you'd want to keep. We favour warm paper neutrals over cool greys, serifs over geometric sans, and soft glows over harsh shadows. Every surface should feel considered — like it was chosen, not defaulted.

Gold on cream. One palette.

Gold and cream carry the brand across every Build The Day property. Click any swatch to copy its hex.

Gold scale — primary

Cream scale — warm neutral

Signature accent

Playfair Display & Inter.

Serif headings set the tone; a humanist sans handles the detail. The system monospace stack tags the metadata — dates, labels, numbers — with quiet editorial precision.

One mark. Five voices.

The Build The Day mark is a serif B inside a rounded gold tile. Use the gradient by default. Reach for the mono treatments only when production constraints (single-ink print, embossing, dark surfaces) demand it.

Nuxt UI, wearing Build The Day.

We style on top of Nuxt UI v4 — the primary colour is gold and the neutral scale is stone, so every primitive signs the brand out of the box. Click Components in the header for the full index.

Generous by default.

Container caps at 1200px. Sections breathe at 7rem vertical rhythm on desktop, scaling down to 4rem on phones. Card radius is 1rem, inputs 0.75rem, pills 999px.

Warm, confident, specific, quiet.

We speak to people planning one of the most specific days of their lives. Write as if the reader has already decided — we're here to make the details easy, not to sell the idea. Four words anchor every line.

In context

• Onboarding

  "Tell us the date. The rest takes care of itself."

  "Begin your magical wedding planning journey today by signing up!"

• Empty state

  "No guests yet. Add one to start the list."

  "It seems your guest list is currently empty. Why not add some guests?"

• Confirmation toast

  "Saved."

  "Your changes have been successfully saved to the database."

• Error

  "That email’s already on the list. Want to update them instead?"

  "Operation failed: duplicate entity detected (code 409)."

• Marketing headline

  "Beautiful wedding websites, without the busywork."

  "The most amazing all-in-one platform for wedding planning ever made!"

Words we use · words we don't

On a phone. In an inbox. On a feed.

The brand has to hold up at every scale — a 38 px home screen tile, a 540 px email column, a 1080-square Instagram post. Same gold, same serif, same quiet.

The third surface.

We paint on three surfaces. Cream paper is the default, the one we use everywhere. Stone-900 is the rare inversion. And sometimes a real wedding photo carries the section itself — the brand still signs it through type, overlay and accent.

GOAL
Make the surface feel like an invitation worth keeping — warm paper, gold leaf, generous air. Quiet luxury.

Rules of the day.

A short list. Break one only with a reason you can name.

• Pair Playfair Display headings with Inter body for elegant contrast.
  Mix three serif fonts in one layout — it fights the hierarchy.
• Use gold-600 (#b87520) as the solid primary; keep it for one job per view.
  Colour large surfaces with gold-600 — it flattens to beige at scale.
• Reach for cream-50 before pure white. Paper, not printer paper.
  Use pure #ffffff as the page background — it looks clinical.
• Round cards to 1rem (16px) and inputs to 0.75rem (12px).
  Use sharp 0px corners anywhere in a celebration context.
• Let the page breathe — generous spacing is the voice of luxury.
  Cram dense tables into narrow columns. Give data room to rest.
