# Hello Monday

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

Hello Monday uses a light canvas (#FFFFFF) with a monochrome palette. Type is set in **Clarendon BTWXX** (display), **NB Internationalproregular**, with 19px body text. Layout: 1299px container, none-detected navigation, 2 sections. Built with gsap, lenis, contentful, 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` | `#FFFFFF` | 1 0 0 | bg | 47.6% | — |
| `surface` | `#F8F6F5` | 0.974 0.003 48.7 | surface | 44.1% | — |
| `on-surface` | `#000000` | 0 0 0 | text | 3.1% | — |
| `color-4` | `#191919` | 0.213 0 0 | other | 4.8% | — |
| `color-5` | `#C6C5C5` | 0.824 0.001 17.2 | other | 0.35% | — |

Contrast: text on background 21:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Clarendon BTWXX** (CSS: `ClarendonBTWXX-Light`) | display | 300, 400 | 83.8% | webfont |
| **NB Internationalproregular** (CSS: `nb_internationalproregular`) | body | 400 | 12.1% | webfont |
| **NB Internationalprolight** (CSS: `nb_internationalprolight`) | other | 400 | 4.1% | webfont |

Scale (px): 13, 14, 15, 18, 19, 23, 80, 90. Effective ratio ≈ 1.679. Body 19px at line-height 1.39; display 80px with tracking 0em. Headings are sentence case. On a 390px viewport the body is 15px and display 40px.

## Layout

Spacing follows a 5px base unit; the most used steps are 7, 9, 10, 15, 30, 40, 47, 50, 60, 70.5, 100px. Content sits in a 1299px container. Text density 0.044 (text area / page area).

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

1. **hero** — “Products” (8721px, bg #FFFFFF)
2. **section** — “A booster rocket for digital product teams” (2216px, bg #191919)

## Shapes

Dominant corner radius 0px; radii in use: none. Borders: hairline (1px).

## Do's and Don'ts

- Do keep the palette monochrome; there is no chromatic brand accent on the page.
- Do set body copy in NB Internationalproregular at 19px / 1.39.
- Do use Clarendon BTWXX only for display sizes, not for body text.
- Don't introduce font weights beyond 300, 400.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 0px for most controls.
- Do snap spacing to multiples of 5px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
