Superhuman — Design System

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

Superhuman commissioned a variable face and tuned it by the unit: Super Sans VF at 64px on a precise 540 weight, 26px/460 standfirsts, and lavender #D4C7FF buttons at 8px radius. Split-flap animations and inbox-zero UI carry the speed story — email's luxury tier, with typography engineered to the same hundredths as its keystroke latency.

Tokens

Superhuman's decoded design system: background #FFFFFF, text #292827, accent #D4C7FF, link #D4C7FF, primary #714CB6; type scale h1 64px / h2 26px / body 18px; 4px spacing base; 0px base radius. The single interactive/action color is #D4C7FF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Superhuman — Design System

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

Superhuman commissioned a variable face and tuned it by the unit: Super Sans VF at 64px on a precise 540 weight, 26px/460 standfirsts, and lavender #D4C7FF buttons at 8px radius. Split-flap animations and inbox-zero UI carry the speed story — email's luxury tier, with typography engineered to the same hundredths as its keystroke latency.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F2F2F2` |
| border | `#DEDEDE` |
| text | `#292827` |
| text_muted | `#7A7979` |
| primary | `#714CB6` |
| accent | `#D4C7FF` |
| link | `#D4C7FF` |
| secondary | `#0C4243` |
| button_bg | `#D4C7FF` |
| button_text | `#292827` |

**Using these colors**

- **Action color** `#D4C7FF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link`, `button_bg` are all `#D4C7FF` — one role, not several (your action color).
- **accent** `#D4C7FF` — 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** `#714CB6` — a brand color — but the call-to-action uses #D4C7FF, not this.
- **secondary** `#0C4243` — 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): `#F6F5F1` 79.8% · `#E3E4E7` 11.8% · `#8992A9` 8.3%

## Typography

- Heading: **Super Sans VF** _(free fallback: Newsreader)_
- Body: **Super Sans VF** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 540 · lh 61px |
| h2 | 49px / 460 · lh 59px · tracking -1.35px |
| h3 | 48px / 460 · lh 46px |
| body | 14px / 460 · lh 21px |
| small | 12px / 700 · lh 18px |

- Weight ladder: 460 · 500 · 540 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Super Sans VF may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 16px, 20px, 24px, 26px, 32px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 0px
- button: 8px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#714CB6` / `#292827` | none | 8px | 6px 16px 6px 16px | 600 14px | none |
| secondary | `rgba(255, 255, 255, 0)` / `#714CB6` | none | 12px | 6px 20px 6px 20px | 600 16px | rgb(113, 76, 182) 0px 0px 0px 1px inset |

**States (measured, not guessed)**

- primary hover: background `#BEA1F5`
- primary focus: background `#D4C7FF` · outline `2px solid rgb(59, 150, 255)`
- secondary hover: box-shadow `rgb(83, 49, 146) 0px 0px 0px 2px inset` · color `#533192`
- transition: `background-color 0.2s ease-in-out`

## Shadows (elevation)
- subtle: `color(srgb 0.0784314 0.0784314 0.0745098 / 0.08) 0px 1px 2px 0px`
- card: `color(srgb 0.0784314 0.0784314 0.0745098 / 0.24) 0px 1px 2px 0px, rgb(53, 48, 136) 0px 0px 0px 1px`

## Motion
- durations: 200ms (dominant) · 300ms · 500ms
- easings: `ease` (dominant) · `ease-in-out`
- animated properties: color, translate, rotate, background-color

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

## Motion choreography (measured)
Load order: `span.hero-button_iconContaine` @0ms → `h1.text_text__RO8_0`×2 @257ms → `figure.full-bleed` @258ms → `div.hero-card_card__SIZev`×7 @258ms → `picture.asset-grid_asset__ti5n_`×10 @258ms → `video.hero-background-video_vi` @845ms
- `div.hero-card_card__SIZev` ×7 — opacity 0→1 · scale 0→1 — 300ms cubic-bezier(0.191, 0.703, 0.704, 0.952) (delay 100ms)
- stagger: `div` ×7 — 100ms apart
- overlay dropdown (auto-opened): panel #FFFFFF · r 16px · shadow 

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

## Responsive (measured)
- breakpoints: 640px · 1080px · 1280px · 1440px
- mobile (390px): hero 32px · body 16px · nav: hamburger

## 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.
