Ultrahuman — Design System

light · modern · high · custom · confidence 92% · deep decode

Ultrahuman shoots metabolic wearables like a title fight: Graphik at 80px/500 ('Powering world champions') over black-and-white athlete film, 16px body, and zero-radius text CTAs. Ring hardware macro shots and glucose curves alternate with editorial restraint — health tracking framed as elite-performance journalism rather than wellness pastel.

Tokens

Ultrahuman's decoded design system: background #FFFFFF, text #000000, accent #0882FF, link #007FF5, primary #0882FF; type scale h1 80px / h2 40px / body 16px; 4px spacing base; 20px base radius. The single interactive/action color is #0882FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0882FF — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, button_bg are all #0882FF — one role, not several (the action color).
• accent #0882FF — 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.
• link #007FF5 — inline text links and link-styled controls.
• secondary #0279E8 — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Ultrahuman — Design System

> light, modern, high, custom — deep decode (measured live)

Ultrahuman shoots metabolic wearables like a title fight: Graphik at 80px/500 ('Powering world champions') over black-and-white athlete film, 16px body, and zero-radius text CTAs. Ring hardware macro shots and glucose curves alternate with editorial restraint — health tracking framed as elite-performance journalism rather than wellness pastel.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0882FF` |
| accent | `#0882FF` |
| link | `#007FF5` |
| secondary | `#0279E8` |
| button_bg | `#0882FF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#0882FF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `primary`, `accent`, `button_bg` are all `#0882FF` — one role, not several (your action color).
- **accent** `#0882FF` — 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.
- **link** `#007FF5` — inline text links and link-styled controls.
- **secondary** `#0279E8` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FAFAFA` 65.8% · `#585449` 9.6% · `#76746D` 8.9% · `#1E285F` 8.4%

## Typography

- Heading: **Graphik** _(free fallback: Inter)_
- Body: **Graphik** _(free fallback: Inter)_
- Mono: **JetBrains Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 40px / 500 · lh 48px · tracking -2px |
| h2 | 36px / 500 · lh 43px · tracking -1.44px |
| h3 | 24px / 500 · tracking -0.4px |
| body | 16px / 500 · lh 16px · tracking -0.6px |
| small | 14px / 500 · lh 21px |
| eyebrow | 12px / 400 · tracking 0.6px |

- Weight ladder: 400 · 500 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Graphik is proprietary — closest free match: Inter (Google). Load Inter; keep Graphik first so licensed users still get it.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 10px, 12px, 16px, 24px, 32px, 40px, 64px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 20px
- button: 50px
- card: 50px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#007FF5` / `#FFFFFF` | none | 24px | 8px 16px 7px 16px | 500 16px / -0.6px | none |
| secondary | `#EDEDED` / `#000000` | none | 50px | — | — | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`

## Motion
- durations: 200ms (dominant) · 300ms · 100ms
- easings: `ease-in-out` (dominant) · `ease-out`
- animated properties: transform, opacity

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

## Their own tokens (verbatim from :root)

| Token | Value |
|-------|-------|
| `--font-inter` | `"Inter", system-ui, sans-serif` |
| `--font-graphik-italic` | `"graphikItalic", system-ui, sans-serif` |
| `--font-jetbrains-mono` | `"JetBrains Mono", monospace` |
| `--font-graphik` | `"graphik", "graphik Fallback", system-ui, sans-serif` |
| `--grid-column-gap` | `48px` |
| `--viewportHeight` | `900px` |

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1320px · common grid: 2-col
- nav: 48px relative

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | — | — | 0/0 | — |
| 900 | 675 | — | — | 0/0 | — |
| 1575 | 855 | 2 | — | 40/40 | 86/14 |
| 2430 | 826 | — | — | 8/8 | — |
| 3256 | 826 | — | — | 8/8 | — |
| 4082 | 826 | — | — | 8/8 | — |

## Motion choreography (measured)
Load order: `div.cold` @0ms → `p.sc-433c8452-4` @1ms → `button.sc-89dce803-0`×2 @178ms → `button.sc-89dce803-0`×2 @180ms → `span.ring`×3 @180ms
- `p.sc-433c8452-4` — opacity 0→1 — 500ms ease
- `span.ring` ×3 — opacity 1→0 · transform translate(-50%, -50%) scale(0)→translate(-50%, -50%) scale(1.5) — 1500ms ease-out
- stagger: `span` ×3 — 500ms apart

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

## Components (measured)
- disabled: bg #C2C2C2 · text rgba(16, 16, 16, 0.3)

## Responsive (measured)
- breakpoints: 576px · 768px · 992px · 1024px · 1200px · 1400px
- mobile (390px): hero 20px · body 10px · 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.
