# Plausible Analytics

> Extracted from [https://plausible.io/](https://plausible.io/) 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

Plausible Analytics uses a light canvas (#FFFFFF) with a palette led by #5850EC. Type is set in **SF Pro (system-ui)** (display + body), with 18px body text. Layout: 1120px container, top-static+transparent navigation, 6 sections. Built with tailwind.

## 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` | `#FFFFFF` | 1 0 0 | bg | 65.0% | — |
| `surface` | `#F4F5F7` | 0.97 0.003 264.5 | surface | 10.0% | — |
| `on-surface-variant` | `#4B5563` | 0.446 0.026 256.8 | muted | 3.9% | — |
| `on-surface` | `#161E2E` | 0.235 0.033 263.6 | text | 4.0% | — |
| `primary` | `#5850EC` | 0.538 0.226 277.9 | accent | 1.5% | — |
| `color-6` | `#252F3F` | 0.303 0.032 259.7 | other | 11.6% | — |
| `color-7` | `#6B7280` | 0.551 0.023 264.4 | other | 2.7% | — |
| `color-8` | `#D2D6DC` | 0.875 0.009 258.3 | other | 0.99% | — |
| `color-9` | `#3182CE` | 0.595 0.14 250.3 | other | 0.24% | — |

Sparse chromatic highlights (not accents): `#0E9F6E`.

Contrast: text on background 16.68:1, muted text 7.56:1, accent 5.56:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **SF Pro (system-ui)** (CSS: `system-ui`) | display, body | 400, 500, 600, 700, 800 | 100.0% | system (stack `system-ui, -apple-system, "system-ui", "Segoe UI", Roboto, "`, resolved on macos) |

Scale (px): 12, 14, 16, 18, 20, 24, 30, 36, 48. Effective ratio ≈ 1.217 (close to a minor third). Body 18px at line-height 1.556; display 48px with tracking -0.025em. Headings are sentence case. On a 390px viewport the body is 16px and display 30px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 8, 10, 12, 16, 20, 24, 32, 40, 48, 64, 80, 160px. Sections open with about 112px of space before their first line of text. Content sits in a 1120px container on a 3-column grid. Text density 0.131 (text area / page area).

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

1. **nav** (104px, bg #F9FAFB)
2. **hero** — “Easy to use and privacy-friendly” (1421px, bg #F9FAFB)
3. **section** — “Why use Plausible Analytics?” (652px, bg #FFFFFF)
4. **section** — “People ❤️ Plausible” (2378px, bg #FFFFFF)
5. **pricing** — “Traffic based plans that match your growth” (1114px, bg #F4F5F7)
6. **footer** (676px, bg #252F3F)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.06) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0.1) 0px 4px 6px -1px, rgba(0, 0, 0, 0.06) 0px 2px 4px -1px`
- `rgba(0, 0, 0, 0.25) 0px 25px 50px -12px`

## Shapes

Dominant corner radius 6px; radii in use: 6px, 8px, 12px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#5850EC`, textColor `#FFFFFF`, rounded `6px`, padding `8px 20px`, height `42px`, fontFamily `SF Pro (system-ui)`, fontSize `16px`, fontWeight `500` (e.g. “Start free trial”)
- **card**: rounded `8px`, padding `16px`, border `1px solid #F4F5F7`

## Do's and Don'ts

- Do reserve `#5850EC` for primary actions and highlights; it covers only 1.5% of the painted page.
- Do set body copy in SF Pro (system-ui) at 18px / 1.556.
- Do tighten large headlines (-0.025em at 48px).
- Don't introduce font weights beyond 400, 500, 600, 700, 800.
- Do keep corners at 6px 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.
