# Rive Design System

## Overview

Rive describes itself as: “Behind Duolingo and Spotify Wrapped. Build games, UI, and interactive animation in the Rive Editor or with your coding agent and the Rive CLI.” The interface is dark, built on **Near Black (#000000)** with **White (#FFFFFF)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Orbitron** and **Inter**. Headlines run large with tight negative tracking; body text is 16px. Depth comes from hairline borders and inset highlights rather than drop shadows. Corners are mostly 1.5px.

Measured from [rive.app](https://rive.app/) on October 21, 2026 at 1440×900 and 390×844 from 373 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 13 roles, plus gradient stops #F30058, #FF483C, #FFA41C, #71FF19.

- **Near Black (#000000):** Page background, seen 2 times. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 77 times. Token `on-surface`.
- **Silver (#CCCCCC):** Secondary text, seen 12 times. Token `on-surface-variant`.
- **Silver (#BFBFBF):** Muted text and metadata, seen 4 times. Token `on-surface-muted`.
- **Gray (#999999):** Subtle text and placeholders, seen 28 times. Token `on-surface-subtle`.
- **White 5% (#FFFFFF0D):** Translucent fill for cards and controls, seen 21 times. Token `overlay`.
- **White 30% (#FFFFFF4D):** Stronger translucent fill, seen 14 times. Token `overlay-strong`.
- **White 30% (#FFFFFF4D):** Borders and dividers, seen 32 times. Token `outline`.
- **White 10% (#FFFFFF1A):** Secondary dividers, seen 21 times. Token `outline-variant`.
- **Mist (#E6E6E6):** Primary buttons and calls to action. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **White 90% (#FFFFFFE6):** High-contrast fills, seen 3 times. Token `inverse-surface`.
- **Vivid Green (#71FF19):** Success and positive states, seen 1 time. Token `success`.

## Typography

**Orbitron**, **Inter** and **Tomorrow** share the interface. Fallback stack: `Orbitron, Orbitron Placeholder, sans-serif`. Other loaded fonts: PragmataPro VF Variable Regular, Tomorrow Placeholder, Orbitron Placeholder, PragmataPro VF Variable Regular Placeholder.

- **headline-display:** Orbitron 48px at weight 900, line height 1.02, tracking -0.03em, uppercase (32px on mobile). Page title (h1).
- **headline-lg:** Orbitron 34px at weight 900, line height 1.08, tracking -0.01em, uppercase (26px on mobile). Section headings (h2).
- **body-md:** Inter 16px at weight 400, line height 1.55. Body text.
- **body-sm:** Inter 15px at weight 400, line height 1.55. Secondary and small text.
- **label-lg:** Inter 16px at weight 500, line height 1.2. Large buttons and tabs.
- **label-md:** Tomorrow 14px at weight 500, line height 1.2. Buttons, navigation and labels.
- **label-sm:** Inter 12px at weight 500, line height 1.3, tracking 0.08em, uppercase. Small labels and badges.

## Layout

Spacing does not follow a strict grid: 26% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 4px, sm 6px, md 9px, lg 20px, xl 60px.
- **Sections:** 60px vertical padding between major sections.
- **Gaps:** 10px is the most common gap in flex and grid layouts.
- **Page margin:** 40px on each side of full-width sections.
- **Breakpoints:** 389px, 639px, 640px, 640.98px, 641px, 949px, 949.98px.

## Elevation & Depth

The design avoids drop shadows. Layers are separated by tonal surface steps and hairline rings:

- `rgba(236, 237, 240, 0.7) 0px 1px 0px 0px inset`

## Shapes

Most elements use 1.5px corners. Measured radii, most used first:

- **sm (1.5px):** 180 elements.
- **md (4px):** 100 elements.

## Components

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

- **button-primary (“COPY”):** #FFFFFFE6 fill, #000000 text, 12px/500, 4px radius, padding 5px 9px 6px 9px, border 1px solid #FFFFFF.
- **button-primary-hover:** background #FFFFFF, text #000000 on hover.
- **button-ghost (“Install the Rive CLI from rive.a”):** transparent fill, #000000 text, 12px/400, padding 14px 14px 14px 16px, border 1px solid #FFFFFF40.
- **input-field (“email@rive.app”):** #EBEBEB fill, #000000 text, 16px/400, 8px radius, padding 15px, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 1px inset`.
- **link:** transparent fill, #999999 text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page.
- Do keep text in 4 levels: #FFFFFF, #CCCCCC, #BFBFBF, #999999.
- Do let contrast carry emphasis; primary actions use #E6E6E6 on #000000.
- Do set headlines in Orbitron with tight tracking (-0.03em).
- Do reuse the measured spacing steps (6px, 9px, 20px).
- Do use 1.5px corners on most elements; larger surfaces also use 4px.
- Don't add drop shadows for depth; use hairline rings and borders and contrast.
- Don't introduce new font families beyond Orbitron, Inter and Tomorrow.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.2s, 0.3s. Longer ambient animations run 1.4s.

- **Easing:** `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
