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

WHOOP trains at display weight: Proxima Nova at 120px/400 in white over athlete photography, all-caps CTAs (TRY WHOOP FOR FREE) at 8px radius, and recovery-score greens as the only interface color. The near-monochrome palette and stadium-scale type give the wearable the visual language of elite sport broadcast graphics — data as glory reel.

# Whoop — Design System

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

WHOOP trains at display weight: Proxima Nova at 120px/400 in white over athlete photography, all-caps CTAs (TRY WHOOP FOR FREE) at 8px radius, and recovery-score greens as the only interface color. The near-monochrome palette and stadium-scale type give the wearable the visual language of elite sport broadcast graphics — data as glory reel.

## Colors

| Role | Value |
|------|-------|
| bg | `#000000` |
| surface | `#0E0E0E` |
| border | `#232323` |
| text | `#ECECEE` |
| text_muted | `#929293` |
| primary | `#4A53FF` |
| accent | `#4A53FF` |
| link | `#FF0026` |
| secondary | `#41FF31` |
| button_bg | `#4A53FF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#4A53FF` — 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 `#4A53FF` — one role, not several (your action color).
- **accent** `#4A53FF` — 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** `#FF0026` — inline text links and link-styled controls.
- **secondary** `#41FF31` — 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): `#000000` 73.4% · `#FFFFFF` 12.4% · `#4A53FD` 6% · `#4D657F` 2.6% — the action color covers ~6% of the page; keep it that scarce.

## Typography

- Heading: **Proxima Nova** _(free fallback: Montserrat)_
- Body: **Proxima Nova** _(free fallback: Montserrat)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 120px / 400 · lh 96px · tracking -3.6px |
| h2 | 100px / 400 · lh 85px · tracking -3px |
| h3 | 32px / 600 · lh 35px · tracking -1.2px |
| body | 24px / 500 · lh 26px · tracking -0.96px |
| small | 20px / 400 · lh 26px · tracking -0.6px |
| eyebrow | 14px / 700 · tracking 1.4px |

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

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 25px, 30px — snap all gaps/padding to these

## Radius
- base: 15px
- button: 16px
- card: 24px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#4A53FF` / `#FFFFFF` | none | 16px | 19.9547px 40px 19.9547px 40px | 700 14px / 1.4px | none |
| secondary | `#FFFFFF` / `#000000` | none | 16px | 19.9547px 40px 19.9547px 40px | 700 16px / 1.6px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(74, 83, 255, 0.8)`
- primary focus: background `rgba(74, 83, 255, 0.8)` · outline `2px solid rgb(35, 96, 197)`
- secondary hover: background `#E5E5E5`
- transition: `background-color 0.2s ease`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0.35) 0px 0px 4px 0px`
- card: `rgba(199, 199, 199, 0.25) 0px 4px 15px 0px`

## Motion
- durations: 200ms (dominant) · 250ms · 500ms
- easings: `ease` (dominant) · `cubic-bezier(0.4, 0, 0.2, 1)`
- animated properties: color, background-color, border-color, transform

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-base-sans-serif` | `"proxima-nova","Arial","Helvetica",sans-serif` |

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

## Layout (measured)
- container max 1242px
- nav: 122px fixed · bg #000000

## Motion choreography (measured)
Load order: `div.fifty-fifty-carousel_con` @0ms → `div.sticky-call-to-action_st` @150ms → `a.primary-button_primary-c` @932ms → `a.primary-button_primary-c` @932ms → `div.sticky-call-to-action_st` @1115ms
- `div.sticky-call-to-action_st` — opacity 0→1 · transform translate(-50%, 100px)→translate(-50%) — 500ms ease
- `div.fifty-fifty-carousel_con` — height 0px→100% — 5000ms
- scroll reveal: 7 elements rest at opacity 0, translateY(20px), animate in over 750ms (7 revealed during the drive).
- overlay dialog (auto-opened): panel rgba(0, 0, 0, 0) · r 0px

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

## Components (measured)
- link: #FFFFFF · no underline

## Responsive (measured)
- breakpoints: 550px · 600px · 641px · 896px · 1008px · 1280px
- mobile (390px): hero 50px · 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.
