# Sketch

> Extracted from [https://www.sketch.com/](https://www.sketch.com/) on 2026-11-12 by Emblematic. Every value below was read from the rendered DOM (computed styles, `document.fonts`, and the fonts Chrome actually used to paint text), not estimated from pixels. When the YAML front matter and this prose disagree, the YAML wins. Copy values from this file exactly; don't transcribe them from memory. Don't copy logos, imagery, illustrations or marketing copy.

## Overview

Sketch uses a light canvas (#F5F5F5) with a palette led by #151515. Type is set in **Inter Variable**, **Reckless** (display), with 16px body text. Layout: 1200px container, top-static+transparent navigation, 9 sections. Built with hotwire, netlify, cloudfront.

## Colors

Area-weighted from painted backgrounds, text and borders on the 1440px light capture. Roles are inferred from usage (largest background, most text, interactive fills). Every hex is an exact computed value; a role marked *unverified* is a best guess that has not passed review, so its canonical token (e.g. `primary`) is left out of the front matter.

| Token | Hex | OKLCH | Role | Share of paint | CSS variable |
|---|---|---|---|---|---|
| `background` | `#F5F5F5` | 0.97 0 0 | bg | 67.5% | — |
| `surface` | `#FFFFFF` | 1 0 0 | surface | 10.8% | — |
| `on-surface` | `#212123` | 0.249 0.004 286.1 | text | 7.4% | — |
| `primary` | `#151515` | 0.196 0 0 | accent | 0.64% | — |
| `on-surface-variant` | `#000000A3` (on bg `#585858`) | 0 0 0 | muted | 0.88% | — |
| `outline` | `#0000001A` (on bg `#DDDDDD`) | 0 0 0 | border | 0.02% | — |
| `color-7` | `#000000` | 0 0 0 | other | 6.9% | — |
| `color-8` | `#FFFFFF7A` (on bg `#FAFAFA`) | 1 0 0 | other | 4.1% | — |
| `color-9` | `#5C5C5C` | 0.475 0 0 | other | 0.55% | — |
| `color-10` | `#141D33` | 0.234 0.045 266.2 | other | 0.41% | — |
| `color-11` | `#FFFFFF14` (on bg `#F6F6F6`) | 1 0 0 | other | 0.43% | — |

Sparse chromatic highlights (not accents): `#0000EE`.

Contrast: text on background 14.74:1, muted text 6.51:1, accent 16.75:1.

Gradients in use: `linear-gradient(rgba(0, 0, 0, 0) 0%, rgb(20, 29, 51) 50%)`; `linear-gradient(rgba(0, 0, 0, 0) 0%, rgba(255, 255, 255, 0.05) 50%, rgba(255, 255, 255, 0.15) 100%), none`.

The site does not change under `prefers-color-scheme: dark`.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter Variable** (CSS: `InterVariable`) | body | 400, 500, 600 | 67.0% | webfont |
| **Reckless** | display | 500 | 33.0% | webfont |

Declared in `@font-face` but not used to paint text on this page: Inter Display, Marfa, Caveat, Marfa Mono, Meshed Display. Don't treat these as the page's fonts.

Scale (px): 12, 14, 15, 16, 17, 20, 22, 24, 44, 76. Effective ratio ≈ 1.297 (close to a perfect fourth). Body 16px at line-height 1.5; display 76px with tracking -0.02em. Headings are sentence case. On a 390px viewport the body is 16px and display 48px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 6, 8, 11, 12, 14, 16, 20, 24, 32, 40, 52, 80, 88px. Sections open with about 88px of space before their first line of text. Content sits in a 1200px container on a 2-column grid. Text density 0.084 (text area / page area).

Section order (desktop). Kinds below the review threshold are shown as *section*:

1. **nav** (80px, bg #F5F5F5)
2. **hero** (3051px, bg #F5F5F5)
3. **section** — “Create with focus (or friends)” (536px, bg #000000)
4. **section** — “Test your ideas faster” (1085px, bg #F5F5F5)
5. **section** — “Take your work further” (445px, bg #F5F5F5)
6. **section** — “Easy sharing” (1706px, bg #000000)
7. **section** — “Discover a better way to design” (749px, bg #F5F5F5)
8. **section** (156px, bg #F5F5F5)
9. **footer** — “Never miss an update” (626px, bg #F5F5F5)

## Elevation & Depth

Style: layered. Most used shadows:

- `rgba(0, 0, 0, 0.05) 0px 1px 1px 0px inset, rgba(255, 255, 255, 0.55) 0px 1px 4px 0px inset, rgba(0, 0, 0, 0.94) 0px -2px 4px 0px inset, rgba(0, 0, 0, 0.2) 0px 1px 4px 0px`
- `rgba(0, 0, 0, 0.1) 0px 2px 4px 0px`
- `rgba(0, 0, 0, 0.1) 0px 0.5px 1px 0.5px inset`

## Shapes

Dominant corner radius 20px; radii in use: 3px, 16px, 20px, 26px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#151515`, textColor `#FFFFFF`, rounded `9999px`, padding `11px 16px`, height `47px`, fontFamily `Inter Variable`, fontSize `16px`, fontWeight `600`, shadow `rgba(0, 0, 0, 0.05) 0px 1px 1px 0px inset, rgba(255, 255, 255, 0.55) 0px 1px 4px 0px inset, rgba(0, 0, 0, 0.94) 0px -2px` (e.g. “Get started”)
- **card**: rounded `20px`, padding `32px`, backgroundColor `#FFFFFF`
- **input**: rounded `16px`, height `48px`, padding `12px 14px`, backgroundColor `#F9F9F9`

## Do's and Don'ts

- Do reserve `#151515` for primary actions and highlights; it covers only 0.64% of the painted page.
- Do set body copy in Inter Variable at 16px / 1.5.
- Do use Reckless only for display sizes, not for body text.
- Do tighten large headlines (-0.02em at 76px).
- Don't introduce font weights beyond 400, 500, 600.
- Do keep corners at 20px for most controls, and use the larger radii only for cards and media.
- Do snap spacing to multiples of 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
