# Plain

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

Plain uses a light canvas (#FFFFFF) with a palette led by #1B6646. Type is set in **ABC Favorit** (display + body), **Geist Mono** (mono), with 16px body text. Layout: 1200px container, none-detected navigation, 8 sections. Built with framer, hubspot, posthog, google-tag-manager, vercel.

## 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 |

Sparse chromatic highlights (not accents): `#2C9266` (`--token-06c0d6de-883e-45e9-9b4f-ae9eae1e1e7a`).

Contrast: text on background 14.12:1, muted text 2.99:1, accent 6.92:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **ABC Favorit** (CSS: `ABC Favorit Regular`) | display, body | 400, 500 | 93.5% | webfont |
| **Geist Mono** | mono | 500 | 5.6% | webfont |

Declared in `@font-face` but not used to paint text on this page: Inter, Fragment Mono, Inria Serif, Lato, ABC Whyte, Rothek. Don't treat these as the page's fonts.

Scale (px): 13, 15, 16, 19, 24, 32, 38, 48. Effective ratio ≈ 1.246 (close to a major third). Body 16px at line-height 1.75; display 48px with tracking -0.021em. Headings are sentence case. On a 390px viewport the body is 17px and display 38px.

## Layout

Spacing follows a 8px base unit; the most used steps are 4, 6, 8, 10, 12, 16, 20, 24, 32, 40, 48, 64, 96px. Sections open with about 160px of space before their first line of text. Content sits in a 1200px container on a 3-column grid. Text density 0.081 (text area / page area).

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

1. **section** (70px, bg #FFFFFF)
2. **hero** — “Support infrastructure for humans & agents” (900px, bg #FFFFFF)
3. **section** — “One place where your team and agents work together.” (1869px, bg #FFFFFF)
4. **section** — “Let agents do the work, yours or ours.” (2243px, bg #FFFFFF)
5. **section** — “Your agents, our infrastructure.” (724px, bg #FFFFFF)
6. **section** — “What happens when teams switch to Plain.” (1963px, bg #28060E)
7. **section** — “Get your support running on Plain in minutes.” (591px, bg #193227)
8. **footer** (760px, bg #193227)

## Shapes

Dominant corner radius is a full pill; radii in use: 8px, 12px, 16px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#1B6646`, textColor `#0000EE`, rounded `9999px`, padding `8px 16px`, height `36px`, fontFamily `sans-serif`, fontSize `12px`, fontWeight `400`
- **card**: rounded `8px`, padding `0px`, backgroundColor `#F7F5F3`

## Do's and Don'ts

- Do reserve `#1B6646` for primary actions and highlights; it covers only 0.11% of the painted page.
- Do set body copy in ABC Favorit at 16px / 1.75.
- Do tighten large headlines (-0.021em at 48px).
- Don't introduce font weights beyond 400, 500.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at pill for most controls, and use the larger radii only for cards and media.
- Do snap spacing to multiples of 8px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
