# Railway

> Extracted from [https://railway.com/](https://railway.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

Railway uses a dark canvas (#13111C) with a palette. Type is set in **Inter**, **Menlo** (mono), **IBM Plex Serif** (display), with 16px body text. Layout: 1160px container, none-detected navigation, 8 sections. Built with tailwind, radix-ui, google-tag-manager.

## 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): `#F1CD69`, `#276852`, `#F9A8D4`, `#609F89`.

Declared brand/accent tokens: `--agents-accent` = `#A78BFE` (declared, not painted on this page).

Contrast: text on background 18.67:1, muted text 3.86:1, accent 2.16:1.

Gradients in use: `linear-gradient(rgba(0, 0, 0, 0.3), rgba(0, 0, 0, 0.05))`; `linear-gradient(to top, rgb(49, 60, 60), rgba(40, 52, 52, 0))`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** | body | 400, 500, 600, 700 | 38.1% | webfont |
| **Menlo** (CSS: `ui-monospace`) | mono | 400 | 31.8% | system (stack `ui-monospace, SFMono-Regular, "SF Mono", Consolas, "Liberati`, resolved on macos) |
| **JetBrains Mono** | other | 400, 500 | 15.2% | webfont |
| **IBM Plex Serif** | display | 400, 500 | 14.3% | webfont |

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

Scale (px): 6, 6.5, 11, 11.5, 12, 13, 14, 16, 18, 20, 36, 40, 54. Effective ratio ≈ 1.275 (close to a major third). Body 16px at line-height 1.5; display 54px with tracking -0.036em. Headings are sentence case. On a 390px viewport the body is 16px and display 40px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 8, 12, 16, 20, 24, 32, 40, 48, 64, 80, 96px. Sections open with about 96px of space before their first line of text. Content sits in a 1160px container on a 12-column grid. Text density 0.11 (text area / page area).

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

1. **hero** (3500px, bg #13111C)
2. **section** — “Instant networking. Zero setup.” (765px, bg #13111C)
3. **section** — “Grow big without the growing pains” (3542px, bg #13111C)
4. **section** (236px, bg #13111C)
5. **section** — “Trusted by the best in business” (1535px, bg #251823)
6. **section** — “229.4M + deploys per month (and counting)” (184px, bg #13111C)
7. **section** (2196px, bg #13111C)
8. **footer** — “Legal” (652px, bg #13111C)

## Shapes

Dominant corner radius 4px; radii in use: 4px. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#553F83`, textColor `#FFFFFF`, rounded `8px`, padding `12px 24px`, height `58px`, fontFamily `Inter`, fontSize `20px`, fontWeight `500`, border `1px solid #FFFFFF26` (e.g. “Deploy →”)

## Do's and Don'ts

- Do set body copy in Inter at 16px / 1.5.
- Do use IBM Plex Serif only for display sizes, not for body text.
- Do tighten large headlines (-0.036em at 54px).
- Don't introduce font weights beyond 400, 500, 600, 700.
- Do keep corners at 4px for most controls.
- 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.
