Rules written from the measurements, so a coding agent stays on style.
- Use #ECECEC for the page and lift surfaces in small steps: #F2F2F2, #FFFFFF.
- Keep text in 2 levels: #151515, #000000.
- Reserve #FFAA00 for primary actions and key highlights.
- Set headlines in Liga with tight tracking (-0.022em).
- Keep spacing on the 4px grid.
- Use 40px corners on most elements; larger surfaces also use 12px, 36px and 4px.
- Introduce new font families beyond Liga and Adventure.
- Use #FFAA00 for large backgrounds or body text.
- Make interface transitions slower than 0.3s.

# Rivian Design System
## Overview
Rivian describes itself as: “Discover Rivian's long-range electric vehicles, innovative EV trucks, SUVs and vans built for adventure. Join the movement towards a sustainable future.” The interface is light, built on **Mist (#ECECEC)** with **Charcoal (#151515)** text, and **Vivid Amber (#FFAA00)** as the main accent.
Type is set in **Liga** and **Adventure**. Headlines run large with tight negative tracking; body text is 14px. Depth comes from soft drop shadows. Corners are mostly 40px.
Measured from [rivian.com](https://rivian.com/) on October 21, 2026 at 1440×900 and 390×844 from 269 rendered elements. Values are computed styles from the live page, not the original source files.

- **Scale:** xs 4px, sm 8px, md 16px, lg 20px, xl 40px.
- **Gaps:** 12px is the most common gap in flex and grid layouts.
- **Container:** content is capped at 1920px.
- **Breakpoints:** 640px, 768px, 1024px, 1440px.
## Elevation & Depth
Raised elements use soft drop shadows. The most used recipes:
- `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.15) 0px 2px 8px 0px`
## Shapes
Most elements use 40px corners. Measured radii, most used first:
- **xl (40px):** 132 elements.
- **full (9999px):** 32 elements.
- **md (12px):** 24 elements.
- **lg (36px):** 16 elements.
- **sm (4px):** 8 elements.

## Do's and Don'ts
- Do use #ECECEC for the page and lift surfaces in small steps: #F2F2F2, #FFFFFF.
- Do keep text in 2 levels: #151515, #000000.
- Do reserve #FFAA00 for primary actions and key highlights.
- Do set headlines in Liga with tight tracking (-0.022em).
- Do keep spacing on the 4px grid.
- Do use 40px corners on most elements; larger surfaces also use 12px, 36px and 4px.
- Don't introduce new font families beyond Liga and Adventure.
- Don't use #FFAA00 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.
## Motion
Interface transitions are quick: 0.3s, 0.15s, 0.2s, 0.1s.
- **Easing:** `cubic-bezier(0.83, 0, 0.17, 1)`, `ease`, `cubic-bezier(0.4, 0, 0.2, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.

What you can build with it
Landing pages, pricing tables, dashboards: your AI coding agent builds them in this style, with these colors, fonts, spacing and buttons instead of its defaults.
Download DESIGN.md, put it in your project’s root folder, then ask your agent for a page.
Build a landing page for my product. Follow for every color, font, spacing value, corner and button.
Need more than one page?
Design MD in the Sitepeel tools for Chrome measures pages behind a login, combines several pages into one file and works on any site you open.

Questions
What can I build with the Rivian DESIGN.md?
Any page or component in this style: a landing page, pricing table, dashboard or sign-up form. Your AI coding agent uses the measured colors, Liga type, spacing, corners and buttons instead of its own defaults.
How do I use it with Claude Code or Cursor?
Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.
Is this Rivian’s official design system?
No. Sitepeel measured it from rivian.com’s public page on October 21, 2026. It is an independent analysis, not made or approved by Rivian.
Can I use Rivian’s style in my own product?
Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Rivian’s logo, name, pictures or text.
How accurate are the values?
Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.
