Tokens

Klarna Mobile's decoded design system: background #0B061E, text #FFFFFF, accent #0B061E, link #0B061E, primary #0B061E; type scale h1 34px / h2 22px / body 17px; 4px spacing base; 12px base radius. The single interactive/action color is #0B061E — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #0B061E — the single interactive color; only on things you click or must notice, never large fills.
• primary, accent, link, button_bg are all #0B061E — one role, not several (the action color).
• accent #0B061E — 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.

# Klarna Mobile — Design System

> dark, consumer, high — deep decode (measured live)

Klarna Mobile — palette measured from official store listing screenshots (colors only; no font claims). Type scale shown is the platform HIG default.

## Colors

| Role | Value |
|------|-------|
| bg | `#0B061E` |
| surface | `#19142B` |
| border | `#2F2B3F` |
| text | `#FFFFFF` |
| text_muted | `#A2A0A9` |
| primary | `#0B061E` |
| accent | `#0B061E` |
| link | `#0B061E` |
| button_bg | `#0B061E` |
| button_text | `#0B061E` |

**Using these colors**

- **Action color** `#0B061E` — 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`, `link`, `button_bg` are all `#0B061E` — one role, not several (your action color).
- **accent** `#0B061E` — 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.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 24.1% · `#000001` 18.1% · `#EEEDF5` 15.3% · `#CDBCC2` 13.5%

## Typography


| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 100px / 700 · lh 40px |
| h2 | 84px / 700 · lh 76px |
| h3 | 64px / 700 · lh 62px |
| body | 16px / 400 · lh 24px |
| small | 14px / 500 · lh 16px |

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 8px, 10px, 11px, 12px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 120px top/bottom padding per section (measured)

## Radius
- base: 12px
- button: 12px
- card: 16px
- pill: 9999px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFA8CD` / `#0B051D` | none | 24px | 12px 20px 12px 20px | 500 16px | none |
| secondary | `#0B051D` / `#FFFFFF` | none | 9999px | 10px 20px 10px 20px | 400 16px | none |

**States (measured, not guessed)**

- primary hover: background `#FFD8EA`
- primary focus: box-shadow `rgb(112, 57, 226) 0px 0px 0px 2px` · background `#FFD8EA` · outline `2px solid rgb(11, 5, 29)`
- secondary hover: background `#2C2242`

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

## Motion
- durations: 200ms (dominant) · 300ms · 90ms
- easings: `ease` (dominant) · `linear`
- animated properties: opacity, background-color, border-color, color

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)

_…and 108 more measured on the page._

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

## Layout (measured)
- container max 700px · common grid: 2-col
- nav: 72px

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 4295 | 1351 | — | — | 120/120 | — |
| 4415 | 1111 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.pr-xma6ck`×2 @0ms → `div.pr-1nmwv0e` @1319ms → `div.pr-1nmwv0e` @1319ms → `div.pr-1nmwv0e` @1319ms → `div.pr-1nmwv0e` @1320ms → `div.pr-1s8myht` @1320ms
- `div.pr-xma6ck` — transform translateX(-100%)→translateX(0px) — 5000ms
- stagger: `span` ×5 — 100ms apart
- stagger: `div` ×6 — 100ms apart
- scroll reveal: 19 elements rest at opacity 0, translateY(20px), animate in over 300ms (14 revealed during the drive).

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

## Components (measured)
- link: #0B051D · underline — hover #5C31B8

## Responsive (measured)
- mobile (390px): hero 52px · 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.
