Oura — Design System

light · modern · medium · tailwind · confidence 92% · deep decode

Oura whispers 'Subtle. Power.' in Editorial New at 110px/300 — a hairline serif at billboard scale in warm stone #4A4741 — with Akkurat LL at 16-18px and full-pill text CTAs. Macro ring photography on skin tones does the selling; wearable health styled like a fragrance campaign, which is precisely its premium position.

Tokens

Oura's decoded design system: background #F7F1E8, text #4A4741, accent #2A72DE, link #5B6550, primary #F7F1E8; type scale h1 110px / h2 18px / body 16px; 8px spacing base; 4px base radius. The single interactive/action color is #2A72DE — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #2A72DE — the single interactive color; only on things you click or must notice, never large fills.
• accent, secondary, button_bg are all #2A72DE — one role, not several (the action color).
• accent #2A72DE — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #F7F1E8 — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #2A72DE).
• link #5B6550 — reads as a neutral UI color, not a link accent — verify against the reference (action = #2A72DE).

# Oura — Design System

> light, modern, medium, tailwind — deep decode (measured live)

Oura whispers 'Subtle. Power.' in Editorial New at 110px/300 — a hairline serif at billboard scale in warm stone #4A4741 — with Akkurat LL at 16-18px and full-pill text CTAs. Macro ring photography on skin tones does the selling; wearable health styled like a fragrance campaign, which is precisely its premium position.

## Colors

| Role | Value |
|------|-------|
| bg | `#F7F1E8` |
| surface | `#ECE6DD` |
| border | `#DDD7CE` |
| text | `#4A4741` |
| text_muted | `#8B8780` |

| secondary | `#2A72DE` |
| button_bg | `#2A72DE` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#2A72DE` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `secondary`, `button_bg` are all `#2A72DE` — one role, not several (your action color).
- **accent** `#2A72DE` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#F7F1E8` — a neutral UI color (chips, tags, icon fills, chrome), not the action color (action = #2A72DE).
- **link** `#5B6550` — reads as a neutral UI color, not a link accent — verify against the reference (action = #2A72DE).
- **Page coverage** (full-page screenshot pixels): `#B6B5B1` 29% · `#C4C2C0` 28.5% · `#302A28` 12% · `#FFFFFF` 11.4%

## Typography

- Heading: **Editorial New** _(free fallback: Fraunces)_
- Body: **Akkurat LL** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 110px / 300 · lh 121px · tracking -5.5px |
| h2 | 80px / 300 · lh 100px · tracking -2px |
| h3 | 48px / 200 · lh 48px |
| body | 24px / 400 · lh 30px |
| small | 19px / 600 · lh 25px |
| eyebrow | 18px / 700 · tracking 0.9px |

- Weight ladder: 200 · 300 · 400 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Editorial New is proprietary — closest free match: Fraunces (Google). Load Fraunces; keep Editorial New first so licensed users still get it. Akkurat LL may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 8px, 10px, 12px, 16px, 20px, 24px, 28px, 32px, 40px, 48px — snap all gaps/padding to these
- section rhythm: 64px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 9999px
- card: 8px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#2A72DE` / `#FFFFFF` | none | 3.35544e+07px | 12px 24px 12px 24px | 700 16px | none |
| secondary | `#F7F1E8` / `#4A4741` | none | 9999px | — | — | none |

**States (measured, not guessed)**

- primary focus: outline `2px solid rgb(49, 132, 255)`
- transition: `color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Shadows (elevation)
- card: `rgba(0, 0, 0, 0.2) 0px 0px 18px 0px`

## Motion
- durations: 150ms (dominant) · 300ms · 500ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: opacity, color, background-color, border-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Layout (measured)
- container max 1440px · common grid: 24-col

## Motion choreography (measured)
Load order: `span.text-base`×3 @0ms → `span.text-base`×3 @0ms → `span.text-base`×3 @0ms → `span.text-base`×3 @0ms
- stagger: `div` ×6 — 250ms apart
- scroll reveal: 4 elements rest at opacity 0, animate in over 1000ms (2 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- input: h 40px · r 12px · bg #4A4741 · placeholder #FFFFFF
- card ×3: pad 24px 24px 24px 24px · r 8px · bg #F7F1E8
  - hover: font-weight `400` · letter-spacing `normal`
- link: #FFFFFF · no underline

- mobile (390px): hero 48px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
