# tldraw

> Extracted from [https://www.tldraw.com/](https://www.tldraw.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

tldraw uses a light canvas (#F9FAFB) with a palette led by #3182ED. Type is set in **Inter** (display + body), with 12px body text. Layout: fluid container, none-detected navigation, 1 sections. Built with react, radix-ui, google-tag-manager, vercel, cloudflare.

## 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` | `#F9FAFB` | 0.985 0.002 247.8 | bg | 94.4% | — |
| `on-surface` | `#000000` | 0 0 0 | text | 1.7% | — |
| `surface` | `#0000000B` (on bg `#EEEFF0`) | 0 0 0 | surface | 1.7% | — |
| `on-surface-variant` | `#1C1C1C` | 0.226 0 0 | muted | 0.36% | — |
| `primary` | `#3182ED` | 0.614 0.179 256.9 | accent | 0.21% | — |
| `color-6` | `#EDF0F2` | 0.953 0.004 236.5 | other | 0.72% | — |
| `color-7` | `#2E2E2E` | 0.301 0 0 | other | 0.56% | — |

Contrast: text on background 20.1:1, muted text 16.31:1, accent 3.62:1.

The site responds to `prefers-color-scheme: dark`; the `-dark` tokens hold the dark-mode roles.

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** | display, body | 500, 600, 700 | 100.0% | webfont |

Scale (px): 12, 24.  Body 12px at line-height 1.6; display 24px with tracking 0em. Headings are lower case. On a 390px viewport the body is ?px and display 24px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 4, 8, 12, 16px. Content sits in a fluid container on a 2-column grid. Text density 0.017 (text area / page area).

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

1. **hero** (900px, bg #FCFCFC)

## Elevation & Depth

Style: layered. Most used shadows:

- `rgba(0, 0, 0, 0.16) 0px 0px 2px 0px, rgba(0, 0, 0, 0.24) 0px 2px 3px 0px, rgba(0, 0, 0, 0.1) 0px 2px 6px 0px`

## Shapes

Dominant corner radius 0px; radii in use: 2px, 9px, 11px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#3182ED`, textColor `#FFFFFF`, rounded `0px`, padding `0px 16px`, height `36px`, fontFamily `Inter`, fontSize `12px`, fontWeight `600` (e.g. “Sign in to share”)

## Do's and Don'ts

- Do reserve `#3182ED` for primary actions and highlights; it covers only 0.21% of the painted page.
- Do set body copy in Inter at 12px / 1.6.
- Don't introduce font weights beyond 500, 600, 700.
- Do keep corners at 0px for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.

## Provenance

Spec v2, extractor 0.2.0. Render quality: **ok**. Vision pass: not run. Fields below confidence 0.7 are hedged or left out above: `color.accent_strategy`, `layout.columns`, `layout.hero`, `layout.section_count`, `space.base`, `space.section_padding_px`, `type.ratio`. Full per-field provenance is in `spec.json`.
