# Modern Treasury

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

Modern Treasury uses a light canvas (#FFFFFF) with a palette. Type is set in **Mt Sans**, **Mt Neue Display** (display), **Mt Mono** (mono), with 16px body text. Layout: 1200px container, top-sticky+blur navigation, 10 sections. Built with next.js, tailwind, shadcn/ui, sanity, 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 |
|---|---|---|---|---|---|
| `background` | `#FFFFFF` | 1 0 0 | bg | 57.3% | `--color-module-background` |
| `surface` | `#F8F7F5` | 0.976 0.003 84.6 | surface | 21.4% | `--color-light-beige` |
| `on-surface` | `#151515` | 0.196 0 0 | text | 4.6% | `--color-text-strong` |
| `on-surface-variant` | `#151515CC` (on bg `#444444`) | 0.196 0 0 | muted | 2.5% | `--color-text-default` |
| `outline` | `#FFFFFF33` (on bg `#FFFFFF`) | 1 0 0 | border | 0.13% | `--color-alpha-white-200` |
| `green-950` | `#0C221D` | 0.232 0.03 176.8 | other | 11.1% | `--color-green-950` |
| `color-7` | `#FFFFFFE6` (on bg `#FFFFFF`) | 1 0 39 | other | 1.1% | — |
| `alpha-white-600` | `#FFFFFF99` (on bg `#FFFFFF`) | 1 0 0 | other | 0.64% | `--color-alpha-white-600` |
| `alpha-black-600` | `#15151599` (on bg `#737373`) | 0.196 0 0 | other | 0.37% | `--color-alpha-black-600` |
| `alpha-black-500` | `#15151580` (on bg `#8A8A8A`) | 0.196 0 0 | other | 0.37% | `--color-alpha-black-500` |
| `green-200` | `#BAE0CF` | 0.875 0.046 166.4 | other | 0.07% | `--color-green-200` |

Sparse chromatic highlights (not accents): `#29735C` (`--color-mt-logo`).

Declared brand/accent tokens: `--color-accent` = `#29735C`.

Contrast: text on background 18.26:1, muted text 9.77:1, accent 18.26:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Mt Sans** (CSS: `mt-sans`) | body | 330, 360, 500, 600 | 50.2% | webfont |
| **Mt Neue Display** (CSS: `mt-neue-display`) | display | 450 | 30.6% | webfont |
| **Mt Mono** (CSS: `mt-mono`) | mono | 400, 500 | 9.8% | webfont |
| **Mt Neue Text** (CSS: `mt-neue-text`) | other | 400 | 9.4% | webfont |

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

Scale (px): 10, 11, 12.5, 13, 14, 16, 18, 21, 32, 47, 71. Effective ratio ≈ 1.347 (close to a perfect fourth). Body 16px at line-height 1.5; display 71px with tracking 0em. Headings are title case. On a 390px viewport the body is 16px and display 47px.

## Layout

Spacing follows a 4px base unit; the most used steps are 2, 4, 6, 8, 12, 14, 16, 20, 22, 24, 32, 40, 48, 60px. Sections open with about 120px of space before their first line of text. Content sits in a 1200px container on a 3-column grid. Text density 0.085 (text area / page area).

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

1. **nav** (65px, bg #FEFEFE)
2. **hero** (114px, bg #FEFEFE)
3. **section** — “Build Products That Move Money” (779px, bg #FFFFFF)
4. **section** — “Platform Pay-Ins and Payouts” (1624px, bg #FFFFFF)
5. **section** (325px, bg #FFFFFF)
6. **section** — “One API, from Onboarding to Reconciliation” (853px, bg #FFFFFF)
7. **section** — “Get Live. Keep Building.” (502px, bg #FFFFFF)
8. **testimonials** (416px, bg #FFFFFF)
9. **section** — “Start Moving Money” (784px, bg #FFFFFF)
10. **footer** (712px, bg #0C221D)

## Elevation & Depth

Style: flat. Most used shadows:

- `lab(0 0 0 / 0.04) 0px 20px 25px -5px, lab(0 0 0 / 0.04) 0px 8px 10px -6px`

## Shapes

Dominant corner radius 2px; radii in use: 2px, 8px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#151515`, textColor `#FFFFFF`, rounded `2px`, padding `8px 14px`, height `40px`, fontFamily `Mt Sans`, fontSize `16px`, fontWeight `600`, shadow `rgb(21, 21, 21) 0px 0px 0px 1px inset` (e.g. “Talk to us”)
- **card**: rounded `8px`, padding `0px`, backgroundColor `#F8F5F4`
- **input**: rounded `0px`, height `40px`, padding `8px 12px`, backgroundColor `#FFFFFF`

## Do's and Don'ts

- Do set body copy in Mt Sans at 16px / 1.5.
- Do use Mt Neue Display only for display sizes, not for body text.
- Don't introduce font weights beyond 330, 360, 400, 450, 500, 600.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at 2px 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.
