### What is the Splice DESIGN.md?

A plain-text file with Splice’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.

### 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 Splice’s official design system?

No. Sitepeel measured it from splice.com’s public page on November 5, 2026. It is an independent analysis, not made or approved by Splice.

### Can I use Splice’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 Splice’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.

# Splice Design System

## Overview

Splice describes itself as: “Splice is the industry's highest quality, royalty-free sample library. Get access to millions of sounds made by top artists, labels, and sound designers.” The interface is dark, built on **Near Black (#000000)** with **White (#FFFFFF)** text, and **Vivid Indigo (#0033FF)** as the main accent.

Type is set in **SoehneBreit** and **InterVariable**. Headlines run large; body text is 14px. The surface language is flat. Corners are mostly 8px.

Measured from [splice.com](https://splice.com/) on November 5, 2026 at 1440×900 and 390×844 from 342 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **Near Black (#000000):** Page background. Token `background`.
- **White (#FFFFFF):** Primary text and headings, seen 70 times. Token `on-surface`, CSS `--overlay-100`.
- **Silver (#C8C9CC):** Secondary text, seen 52 times. Token `on-surface-variant`, CSS `--text-02`.
- **Cool Gray (#A6A8AD):** Muted text and metadata, seen 13 times. Token `on-surface-muted`.
- **Charcoal (#121214):** Raised areas one step from the page, seen 3 times. Token `surface-container-low`, CSS `--text-on-inverse`.
- **Graphite (#232426):** Cards and panels, seen 5 times. Token `surface-container`, CSS `--row-background-hover`.
- **Cool Graphite (#45464D):** Borders and dividers, seen 1 time. Token `outline`, CSS `--surface-action-disabled`.
- **Vivid Indigo (#0033FF):** Brand color in the header. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Vivid Blue (#1253FF):** Secondary buttons, seen 10 times. Token `secondary`.
- **Blue (#528FFF):** Accent in text, fills and borders, seen 17 times. Token `tertiary`, CSS `--link-01`.

## Typography

**SoehneBreit** and **InterVariable** share the interface. Fallback stack: `SoehneBreit, -apple-system, BlinkMacSystemFont, Segoe UI`. Other loaded fonts: Soehne.

- **headline-display:** SoehneBreit 48px at weight 400, line height 1.25 (20px on mobile). Page title (h1).
- **headline-lg:** SoehneBreit 36px at weight 400, line height 1.25, tracking -0.011em (28px on mobile). Section headings (h2).
- **headline-md:** SoehneBreit 28px at weight 400, line height 1.25, tracking -0.007em (20px on mobile). Sub-section headings.
- **headline-sm:** InterVariable 20px at weight 700, line height 1.43. Card and feature titles.
- **body-md:** InterVariable 14px at weight 400, line height 1.43. Body text.
- **body-lg:** InterVariable 16px at weight 400, line height 1.5. Lead paragraphs.
- **body-sm:** InterVariable 13px at weight 400, line height 1.43. Secondary and small text.
- **caption:** InterVariable 12px at weight 400, line height 1.43. Captions and fine print.
- **label-md:** InterVariable 16px at weight 500, line height 1.2. Buttons, navigation and labels.
- **label-sm:** InterVariable 14px at weight 700, line height 1.25, tracking -0.002em. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (75% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 20px.
- **Gaps:** 32px is the most common gap in flex and grid layouts.
- **Page margin:** 20px on each side of full-width sections.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#121214 → #232426) and #45464D borders.

## Shapes

Most elements use 8px corners. Measured radii, most used first:

- **sm (8px):** 48 elements.
- **md (64px):** 40 elements.
- **full (9999px):** 20 elements.
- **lg (100px):** 4 elements.

## Components

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

- **button-primary (“Try now”):** #1253FF fill, #FFFFFF text, 18px/500, 64px radius, padding 13.5px 32px.
- **button-primary-hover:** background #0033FF, text #FFFFFF on hover.
- **button-secondary (“Try now”):** #FFFFFF fill, #121214 text, 16px/500, 100px radius, padding 8px 20px, border 1px solid #C8C9CC.
- **button-tertiary (“Play rss_90_vinyl_cut_free_Emin.”):** #232426 fill, #FFFFFF text, 16px/500, 50% radius, padding 7.5px 20px, border 1px solid #63656D.
- **button-ghost (“Play video”):** transparent fill, #FFFFFF text, 16px/500, 8px radius, padding 11.01px 32px, border 1px solid #45464D.
- **link:** transparent fill, #C8C9CC text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page and lift surfaces in small steps: #121214, #232426.
- Do keep text in 3 levels: #FFFFFF, #C8C9CC, #A6A8AD.
- Do use #0033FF as the brand accent: header, logo and key highlights.
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do use 8px corners on most elements; larger surfaces also use 64px and 100px.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond SoehneBreit and InterVariable.
- Don't use #0033FF for large backgrounds or body text.
- Don't make interface transitions slower than 0.2s.

## Motion

Interface transitions are quick: 0.1s, 0.2s. Longer ambient animations run 0.85s, 1.105s.

- **Easing:** `ease-out`, `ease`, `linear(0 0%, 0.008 1.1%, 0.034 2.3%, 0.134 4.9%, 0.264 7.3%, 0.683 14.3%, 0.797 16.5%, 0.89 18.6%, 0.967 20.7%, 1.027 22.8%, 1.073 25%, 1.104 27.3%, 1.123 30.6%, 1.119 34.3%, 1.018 49.5%, 0.988 58.6%, 0.985 65.2%, 1 84.5%, 1 100%)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
