Design System Inspiration of Klarna

Overview

Visual Theme & Atmosphere

Klarna is a payments and shopping company from Stockholm. Its own history begins with "three young Swedish entrepreneurs" and "a brilliant idea back in 2005—but not the best name": Kreditor became Klarna in 2010. It passed a $1 billion valuation in 2012. In September 2025 Klarna Group plc listed on the New York Stock Exchange (NYSE: KLAR). Klarna counts 120 million active consumers, more than 1.2 million merchants and 26 countries.

Its brand guidelines open with "We're not standard. But the new standard", and describe the brand as "Refreshingly different". The site is near-black on white — the ink is a violet-black #0b051d — with Klarna's pink #ffa8cd on surfaces and badges, and a purple scale for accents and focus. Type is Klarna's own Klarna Text and Klarna Title.

What makes it worth reading:

• The ink is the brand. --brand is #0b051d, the top of a ten-step purple scale (--brand10 #efecff … --brand100). Buttons and text use it; hover lifts to --brand90 #2c2242.
• Pink as a surface. --colors-bg-brand and --colors-btn-brand are #ffa8cd: the famous pink fills areas and badges rather than colouring text.
• Two token generations side by side. A kebab-case layer and an older camelCase layer carry the same values — 205 of 207 camelCase names have an exact twin.

Primary tasks

• Shop with Klarna: search products and stores.
• Sign in; manage payments and the app.

Brand Narrative

Klarna grew from a Stockholm startup called Kreditor into a public payments company with 120 million consumers. Its brand calls itself "not standard" and "refreshingly different", and the site keeps that without shouting: violet-black type, pink as a mood rather than a signal, and a purple scale that shows up where attention is needed — links, accents and focus.

Principles

• Black-violet, not black. The ink has a hue.
• Pink is a place. It fills surfaces; it does not colour words.
• States are quiet. A darker pill, a softer link.

Personas

Not researched. No persona claim is made from a UI capture.

Klarna Text (400, 500, 700) and Klarna Title (700), both loaded (document.fonts) and self-hosted at x.klarnacdn.net/ui/fonts/v1.5/. Headings use Klarna Title. Body copy blocks compute to Klarna Text, though <body> itself and some buttons fall back to the system stack.

Layout

• Spacing: 4, 8, 12, 16, 20, 24, 32, 40, 48, 64, 80px.
• Pink and tinted panels break up a white page; buttons are pills.

Components

Measured on klarna.com/se/ (the probe declines the cookie banner with "Avvisa alla" when it shows), focus read under a real Tab key, and a hover counted only when :hover matched.

• Pill button — Logga in: #0b051d, label #f9f8f5, fully round, 42px, 11px 20px, 16px/500. Hover and press lift it to #2c2242. Focus adds outline: 2px solid #0b051d.
• Header link — Shoppa: #0b051d, 13px/500. Hover fades to opacity 0.84, press to 0.68. Focus: a purple inset 0 0 0 1px #7b57d8 ring inside a 2px near-black outline.
• Accordion item — #0b051d, 64px, 16px/400. The same opacity steps; focus a 3px #7b57d8 ring plus the outline.
• Search field — transparent, #0b051d, 14px/400. Nothing measured changes on hover or focus.

Radius

--radius-xs 4 · s 8 · m 12 · 16 · 24 · 32px, and 99999px for pills.

States

Hover: the pill to #2c2242; links and accordion items to opacity 0.84. Press: #2c2242; opacity 0.68. Focus: a 2px near-black outline, with a purple ring on links and accordion items. The search field shows no change. A secondary "Visa fler" pill could not be hovered or focused (unmeasured).

Do's and Don'ts

Do

• Use #0b051d for ink and the main button; lift it to #2c2242 on hover.
• Use pink #ffa8cd as a surface or badge fill.
• Draw focus with the purple #7b57d8 ring and a near-black outline.

Don't

• Don't set body text in pink.
• Don't use pure black as the brand ink; the token is #0b051d.
• Don't mix the camelCase and kebab-case token layers in new work — they duplicate each other.
