### What is the Clay DESIGN.md?

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

No. Sitepeel measured it from clay.com’s public page on November 4, 2026. It is an independent analysis, not made or approved by Clay.

### Can I use Clay’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 Clay’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.

# Clay Design System

## Overview

Clay describes itself as: “Infrastructure to get any data, run agentic workflows, and launch GTM plays.” The interface is dark, built on **Deep Teal (#035D44)** with **Snow (#FEFDFB)** text, and **Vivid Yellow (#CBD810)** as the main accent.

Type is set in **Roobertvf**. 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 12px.

Measured from [clay.com](https://www.clay.com/) on November 4, 2026 at 1440×900 and 390×844 from 374 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 11 roles.

- **Deep Teal (#035D44):** Page background, seen 1 time. Token `background`.
- **Snow (#FEFDFB):** Primary text and headings, seen 2 times. Token `on-surface`, CSS `--loam---web-library_terra-swatches---oat--oat-100`.
- **Near Black (#000000):** Secondary text, seen 46 times. Token `on-surface-variant`.
- **Deep Blue (#001433):** Muted text and metadata, seen 5 times. Token `on-surface-muted`, CSS `--loam---web-library_terra-swatches---blueberry--blueberry-500`.
- **Charcoal (#1B1A18):** Subtle text and placeholders, seen 6 times. Token `on-surface-subtle`.
- **Warm Slate 15% (#7B797426):** Borders and dividers, seen 26 times. Token `outline`.
- **Vivid Yellow (#CBD810):** Primary buttons and calls to action, seen 1 time. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.

- **Dark Yellow (#808000):** Warnings and highlights, seen 2 times. Token `warning`.

## Typography

**Roobertvf** carries the whole interface. Fallback stack: `Roobertvf, Arial, sans-serif`. Other loaded fonts: Roobert, Space Mono, Phosphor.

- **headline-display:** Roobertvf 88px at weight 575, line height 1, tracking -0.04em (41.5px on mobile). Page title (h1).
- **headline-lg:** Roobertvf 48px at weight 500, line height 1, tracking -0.04em (32px on mobile). Section headings (h2).
- **headline-md:** Roobertvf 44px at weight 500, line height 1.1, tracking -0.02em (32px on mobile). Sub-section headings.
- **headline-sm:** Roobertvf 24px at weight 400, line height 1.3. Card and feature titles.
- **title-lg:** Roobertvf 20px at weight 400, line height 1.3. Small titles.

- **label-sm:** Roobertvf 12px at weight 600, line height 1.1, tracking 0.12em. Small labels and badges.

## Layout

Spacing is mostly on a 4px grid (73% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 2.08px, sm 8px, md 16px, lg 20px, xl 64px.
- **Sections:** 64px vertical padding between major sections.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Breakpoints:** 479px, 767px, 768px, 991px, 1280px.

## Elevation & Depth

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

- `rgba(255, 255, 255, 0.05) 0px 0px 0px 1px inset`

## Shapes

Most elements use 12px corners. Measured radii, most used first:

- **sm (12px):** 216 elements.
- **md (18px):** 132 elements.
- **lg (24px):** 24 elements.

## Components

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

- **button-primary (“Get a demo”):** #CBD810 fill, #000000 text, 18px/500, 12px radius, padding 9px 18px.
- **button-secondary (“Start free trial”):** #FFFFFF fill, #000000 text, 18px/500, 12px radius, padding 9px 18px.
- **button-tertiary (“Start free trial”):** #000000 fill, #FFFFFF text, 13.92px/500, 12px radius, padding 8px 16px.
- **button-ghost (“⌘ K”):** transparent fill, #000000 text, 12.8px/400, padding 6.4px.
- **input-field (“Find companies with 30+ sales re”):** #FFFFFF fill, #1B1A18 text, 16px/400, 20px radius, padding 11.2px 16px 16px 16px.
- **card:** #FEFDFB fill, #000000 text, 16px/400, 18px radius, padding 16px 20px, border 1px solid #FFFFFF.
- **link:** transparent fill, #55534E text, padding 0px.

## Do's and Don'ts

- Do use #035D44 for the page.
- Do keep text in 4 levels: #FEFDFB, #000000, #001433, #1B1A18.
- Do reserve #CBD810 for primary actions and key highlights.
- Do set headlines in Roobertvf with tight tracking (-0.04em).
- Do reuse the measured spacing steps (8px, 16px, 20px).
- Do use 12px corners on most elements; larger surfaces also use 18px and 24px.
- Don't use #000000 for body text; it reaches 2.65:1 on #035D44. Keep it for large text or metadata.
- Don't use #001433 for body text; it reaches 2.31:1 on #035D44. Keep it for large text or metadata.
- Don't add drop shadows for depth; use hairline rings and borders and contrast.
- Don't introduce new font families beyond Roobertvf.
- Don't use #CBD810 for large backgrounds or body text.
- Don't make interface transitions slower than 0.3s.

## Motion

Interface transitions are quick: 0.1s, 0.3s, 0.15s, 0.25s.

- **Easing:** `ease-out`, `cubic-bezier(0.075, 0.82, 0.165, 1)`, `linear`.
