# Stripe Design System

## Overview

Stripe describes itself as: “Stripe is a financial services platform that helps all types of businesses accept payments, build flexible billing models and manage money movement.” The interface is light, built on **White (#FFFFFF)** with **Deep Blue (#061B31)** text, and **Vivid Indigo (#533AFD)** as the main accent.

Type is set in **sohne-var**. Headlines run large with tight negative tracking; body text is 16px. The surface language is flat. Corners are mostly 4px.

Measured from [stripe.com](https://stripe.com/in) on October 21, 2026 at 1440×900 and 390×844 from 467 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 18 roles, plus gradient stops #DA4BFECC, #FF8C6CCC, #8A35DF, #715CFFCC.

- **White (#FFFFFF):** Page background, seen 10 times. Token `background`, CSS `--hds-color-util-bg-min`.
- **Deep Blue (#061B31):** Primary text and headings, seen 64 times. Token `on-surface`, CSS `--hds-color-heading-solid`.
- **Blue (#50617A):** Secondary text, seen 15 times. Token `on-surface-variant`.
- **Blue (#64748D):** Muted text and metadata, seen 27 times. Token `on-surface-muted`, CSS `--hds-color-heading-subdued`.
- **Blue (#7D8BA4):** Subtle text and placeholders, seen 7 times. Token `on-surface-subtle`, CSS `--hds-color-input-text-placeholder`.
- **Snow (#F8FAFD):** Raised areas one step from the page, seen 2 times. Token `surface-container-low`, CSS `--hds-color-util-bg-quiet`.
- **Cool Snow (#F5F5FF):** Cards and panels, seen 2 times. Token `surface-container`.
- **Cool Mist (#E5EDF5):** Hover and pressed fills, seen 4 times. Token `surface-container-high`, CSS `--hds-color-util-neutral-50`.
- **Pale Blue (#E3ECF7):** Highest raised elements, seen 3 times. Token `surface-container-highest`.
- **Cool Mist (#E5EDF5):** Borders and dividers, seen 6 times. Token `outline`, CSS `--hds-color-util-neutral-50`.
- **Pale Indigo (#E2E4FF):** Secondary dividers, seen 3 times. Token `outline-variant`.
- **Vivid Indigo (#533AFD):** Primary buttons and calls to action, seen 49 times. Token `primary`, CSS `--hds-color-accent-border-solid`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Deep Indigo (#1C1E54):** Brand accent (CSS variable), seen 12 times. Token `secondary`.
- **Light Indigo (#7389FF):** Most used accent color, seen 5 times. Token `tertiary`.
- **Vivid Amber (#FBBC05):** Warnings and highlights, seen 1 time. Token `warning`.
- **Vivid Red (#EA4335):** Errors and destructive states, seen 1 time. Token `error`.
- **Green (#34A853):** Success and positive states, seen 1 time. Token `success`.

## Typography

**sohne-var** carries the whole interface. Fallback stack: `sohne-var, SF Pro Display, sans-serif`.

- **headline-display:** sohne-var 48px at weight 300, line height 1.15, tracking -0.02em (34px on mobile). Page title (h1).
- **headline-lg:** sohne-var 32px at weight 300, line height 1.1, tracking -0.02em (22px on mobile). Section headings (h2).
- **headline-md:** sohne-var 26px at weight 300, line height 1.12, tracking -0.01em (20px on mobile). Sub-section headings.
- **headline-sm:** sohne-var 22px at weight 300, line height 1.1, tracking -0.01em. Card and feature titles.
- **body-md:** sohne-var 16px at weight 300, line height 1.25. Body text.
- **body-lg:** sohne-var 18px at weight 300, line height 1.4. Lead paragraphs.
- **body-sm:** sohne-var 14px at weight 400, line height 1. Secondary and small text.
- **caption:** sohne-var 12px at weight 300, line height 1.45. Captions and fine print.
- **label-md:** sohne-var 16px at weight 400. Buttons, navigation and labels.

## Layout

Spacing is mostly on a 4px grid (77% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 24px, xl 64px.
- **Gaps:** 8px is the most common gap in flex and grid layouts.
- **Page margin:** 16px on each side of full-width sections.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#F8FAFD → #F5F5FF → #E5EDF5 → #E3ECF7) and #E5EDF5 borders.

## Shapes

Most elements use 4px corners. Measured radii, most used first:

- **sm (4px):** 132 elements.
- **md (6px):** 12 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Contact sales”):** #533AFD fill, #FFFFFF text, 14px/400, 4px radius, padding 11.5px 20px 12.5px 20px.
- **button-primary-hover:** background #4032C8, text #FFFFFF on hover.
- **button-outline (“Sign in Sign in”):** transparent fill, #533AFD text, 14px/400, 4px radius, padding 10.5px 20px 13.5px 20px, border 1px solid #FFFFFF.
- **button-outline-hover:** background #FFFFFF, text #2E2B8C on hover.
- **button-ghost (“Products”):** transparent fill, #061B31 text, 14px/400, 4px radius, padding 12px 0px.
- **link:** transparent fill, #533AFD text, padding 0px.

## Do's and Don'ts

- Do use #FFFFFF for the page and lift surfaces in small steps: #F8FAFD, #F5F5FF, #E5EDF5, #E3ECF7.
- Do keep text in 4 levels: #061B31, #50617A, #64748D, #7D8BA4.
- Do reserve #533AFD for primary actions and key highlights.
- Do set headlines in sohne-var with tight tracking (-0.02em).
- Do reuse the measured spacing steps (8px, 16px, 24px).
- Do use 4px corners on most elements; larger surfaces also use 6px.
- Don't use #7D8BA4 for body text; it reaches 3.4:1 on #FFFFFF. Keep it for large text or metadata.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond sohne-var.
- Don't use #533AFD for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.3s, 0.15s, 0.1s, 0.2s.

- **Easing:** `cubic-bezier(0.25, 1, 0.5, 1)`, `linear`, `ease`.
