# Darkroom Engineering Design System

## Overview

Darkroom Engineering describes itself as: “We're a global design and development studio shipping fast, motion-rich, and scalable digital work. WebGL, headless builds, and open source tools.” The interface is dark, built on **Near Black (#000000)** with **White (#FFFFFF)** text, and **Vivid Red (#E71419)** as the main accent.

Type is set in **therma**, with **mono** for code. Headlines run large with tight negative tracking; body text is compact. The surface language is flat. Corners are square.

Measured from [darkroom.engineering](https://darkroom.engineering/) on November 4, 2026 at 1440×900 and 390×844 from 401 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 6 roles.

- **Near Black (#000000):** Page background, seen 8 times. Token `background`.
- **White (#FFFFFF):** Primary text and headings. Token `on-surface`.
- **Deep Red (#390205):** Borders and dividers, seen 29 times. Token `outline`.
- **Vivid Red (#E71419):** Links and interactive text, seen 206 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Red (#BA0E12):** Accent in text, fills and borders, seen 3 times. Token `secondary`.

## Typography

**therma** and **mono** (monospace) share the interface. Fallback stack: `therma, thermaExt, therma Fallback`. Other loaded fonts: sauce, monoExt.

- **headline-display:** therma 200px at weight 400, line height 0.8, tracking -0.05em, uppercase (104px on mobile). Page title (h1).
- **headline-lg:** therma 120px at weight 700, line height 0.8, tracking -0.05em, uppercase (75px on mobile). Section headings (h2).
- **code:** mono 14px at weight 200, line height 1.2, tracking -0.01em, uppercase. Code and technical values.

## Layout

Spacing follows a 4px grid: 94% of measured gaps and paddings are multiples of 4px.

- **Scale:** xs 4px, sm 8px, md 16px, lg 24px, xl 40px.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Page margin:** 16px on each side of full-width sections.
- **Breakpoints:** 799.98px, 800px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from color contrast and #390205 borders.

## Shapes

Corners are square. Measured radii, most used first:

- **none (0px):** measured.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-ghost (“SATUS”):** transparent fill, 120px/700, padding 0px.
- **link:** transparent fill, #E71419 text, padding 0px.

## Do's and Don'ts

- Do use #000000 for the page.
- Do use #E71419 for links and interactive text.
- Do set headlines in therma with tight tracking (-0.05em).
- Do keep spacing on the 4px grid.
- Don't add drop shadows for depth; use borders and contrast.
- Don't introduce new font families beyond therma and mono.
- Don't use #E71419 for large backgrounds or body text.
- Don't make interface transitions slower than 0.35s.

## Motion

Interface transitions are quick: 0.15s, 0.2s, 0.12s, 0.001s.

- **Easing:** `cubic-bezier(0.23, 1, 0.32, 1)`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
