### What is the DEPTH design system?

The design system on this page is depth.fyi’s, as measured on November 6, 2026: Inter type, #FFFFFF as the main color and pill-shaped corners, written down as a DESIGN.md. It is not DEPTH’s own documentation.

### What is DEPTH built with?

DEPTH’s website (depth.fyi) is built with Cloudflare, Fastly, GitHub Pages, GSAP and Three.js. The full tech stack Sitepeel found: GSAP, Three.js, Cloudflare, Fastly, Cloudflare Web Analytics and GitHub Pages. Measured on November 6, 2026.

### What is the DEPTH DESIGN.md?

A plain-text file with DEPTH’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 DEPTH’s official design system?

No. Sitepeel measured it from depth.fyi’s public page on November 6, 2026. It is an independent analysis, not made or approved by DEPTH.

### Can I use DEPTH’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 DEPTH’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.

# DEPTH Design System

## Overview

DEPTH describes itself as: “Create studio-quality 3D renders directly in Figma with DEPTH, a real-time 3D studio for forms, materials, lighting, and environments.” The interface is dark, built on **Near Black (#000000)** with **Silver (#CDCED0)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Inter**, with **ui-monospace** for code. Headlines run large; body text is 16px. Depth comes from hairline borders and inset highlights rather than drop shadows. Controls are pill-shaped.

Measured from [depth.fyi](https://depth.fyi/) on November 6, 2026 at 1440×900 and 390×844 from 115 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 10 roles.

- **Near Black (#000000):** Page background, seen 1 time. Token `background`.
- **Silver (#CDCED0):** Primary text and headings. Token `on-surface`.
- **Warm Slate (#6F6B64):** Secondary text, seen 17 times. Token `on-surface-variant`.
- **Near Black (#020407):** Raised areas one step from the page, seen 2 times. Token `surface-container-low`.
- **Charcoal (#151515):** Cards and panels, seen 2 times. Token `surface-container`.
- **Charcoal 18% (#1111112E):** Borders and dividers, seen 4 times. Token `outline`.
- **White 13% (#FFFFFF21):** Secondary dividers, seen 1 time. Token `outline-variant`.
- **White (#FFFFFF):** Primary buttons and calls to action, seen 5 times. Token `primary`.
- **Cool Charcoal (#080B0F):** Text and icons on primary. Token `on-primary`.
- **Warm Mist (#F4F2EC):** High-contrast fills, seen 2 times. Token `inverse-surface`.

## Typography

**Inter** and **ui-monospace** (monospace) share the interface. Fallback stack: `Inter, ui-sans-serif, -apple-system, BlinkMacSystemFont`.

- **headline-display:** Inter 44.5px at weight 330, line height 1.08, tracking 0.045em (23.5px on mobile). Page title (h1).
- **body-md:** Inter 16px at weight 400. Body text.
- **body-sm:** Inter 10px at weight 400. Secondary and small text.
- **caption:** Inter 9px at weight 400, tracking 0.04em. Captions and fine print.
- **label-lg:** Inter 13px at weight 590. Large buttons and tabs.
- **label-md:** Inter 9px at weight 590. Buttons, navigation and labels.
- **label-sm:** Inter 8px at weight 560, tracking 0.08em. Small labels and badges.
- **code:** ui-monospace 8px at weight 400, tracking 0.055em. Code and technical values.

## Layout

Spacing does not follow a strict grid: 37% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 3.84px, sm 6.08px, md 16px, lg 28.8px.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Page margin:** 28.8px on each side of full-width sections.

## Elevation & Depth

Depth comes mostly from hairline rings and inset highlights on tonal surfaces (#020407 → #151515):

- `rgba(255, 255, 255, 0.32) 0px 0px 0px 1px inset`
- `rgba(255, 255, 255, 0.06) 0px 1px 0px 0px inset`

A few raised panels add a soft drop shadow: `rgba(0, 0, 0, 0.24) 0px 20px 64px 0px, rgba(255, 255, 255, 0.07) 0px 1px 0px 0px inset`.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 20 elements.
- **sm (80px):** 4 elements.
- **md (180px):** 4 elements.

## Components

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

- **button-primary (“Open in Figma”):** #FFFFFF fill, #080B0F text, 13px/480, 80px radius, padding 0px 14.4px 0px 18.4px, border 1px solid #FFFFFFDB, shadow `rgba(255, 255, 255, 0.06) 0px 1px 0px 0px inset`.
- **button-primary-hover:** background #DFF7FB, text #071014 on hover.
- **button-ghost (“View Ripple ↗”):** transparent fill, #111111 text, 9.28px/590, padding 0px 0px 0px 12px.
- **card:** transparent fill, #151515 text, 16px/400, padding 0px, border 1px solid #DEDBD4.
- **link:** transparent fill, #151515 text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page and lift surfaces in small steps: #020407, #151515.
- Do keep text in 2 levels: #CDCED0, #6F6B64.
- Do let contrast carry emphasis; primary actions use #FFFFFF on #000000.
- Do reuse the measured spacing steps (6.08px, 16px, 28.8px).
- Do make buttons and chips fully rounded (9999px); most other elements use 80px corners.
- Don't use #6F6B64 for body text; it reaches 3.96:1 on #000000. Keep it for large text or metadata.
- Don't use heavy drop shadows; keep depth to hairline rings and tonal surfaces.
- Don't introduce new font families beyond Inter and ui-monospace.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.42s.

## Motion

Interface transitions are quick: 0.08s, 0.18s, 0.32s, 0.42s. Longer ambient animations run 0.62s.

- **Easing:** `ease`, `linear`, `cubic-bezier(0.22, 1, 0.36, 1)`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
