# Tuple

> Extracted from [https://tuple.app/](https://tuple.app/) 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

Tuple uses a light canvas (#FFFFFF) with a palette led by #6A5ED9. Type is set in **Inter** (display + body), **DM Mono** (mono), with 16px body text. Layout: 1152px container, top-sticky+transparent navigation, 8 sections. Built with astro, tailwind, posthog, google-tag-manager, netlify.

## 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 | 65.7% | `--tw-ring-offset-color` |
| `on-surface` | `#27272A` | 0.274 0.005 286 | text | 12.3% | — |
| `on-surface-variant` | `#71717A` | 0.552 0.014 285.9 | muted | 3.0% | — |
| `surface` | `#E4E4E7` | 0.92 0.004 286.3 | surface | 1.8% | — |
| `primary` | `#6A5ED9` | 0.559 0.182 283.2 | accent | 0.36% | — |
| `outline` | `#52525B` | 0.442 0.015 285.8 | border | 0.10% | — |
| `color-7` | `#09090B` | 0.141 0.004 285.8 | other | 9.4% | — |
| `color-8` | `#EDEFF2` | 0.951 0.005 258.3 | other | 2.7% | — |
| `color-9` | `#35353B` | 0.331 0.01 285.8 | other | 1.4% | — |
| `color-10` | `#DB5434` | 0.62 0.176 34.6 | other | 0.70% | — |

| `color-12` | `#3F3F46` | 0.37 0.012 285.8 | other | 0.51% | — |
| `color-13` | `#A1A1AA` | 0.712 0.013 286.1 | other | 0.35% | — |

Sparse chromatic highlights (not accents): `#DB5434`, `#1BB152`, `#ADB6F4`, `#4ADE80`.

Contrast: text on background 14.89:1, muted text 4.83:1, accent 4.98:1.

Gradients in use: `radial-gradient(closest-corner, rgb(237, 239, 242) 0%, rgba(0, 0, 0, 0) 50%, rgba(0, 0, 0, 0) 100%)`; `linear-gradient(rgb(255, 255, 255), rgb(250, 250, 250), rgb(250, 250, 250))`.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Inter** (CSS: `Inter Variable`) | display, body | 400, 500, 600 | 85.4% | webfont |
| **DM Mono** | mono | 400, 500 | 14.5% | webfont |

Scale (px): 12, 13, 14, 16, 18, 20, 24, 48, 60. Effective ratio ≈ 1.303 (close to a perfect fourth). Body 16px at line-height 1.625; display 60px with tracking 0em. Headings are sentence case. On a 390px viewport the body is 16px and display 30px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 6, 8, 10, 12, 16, 24, 32, 40, 48, 64, 112, 128px. Sections open with about 128px of space before their first line of text. Content sits in a 1152px container on a 3-column grid. Text density 0.076 (text area / page area).

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

1. **nav** — “Tuple” (91px, bg #FFFFFF)
2. **hero** — “Screen sharing for people who build software.” (1618px, bg #FFFFFF)
3. **section** — “Built for working, not for meetings” (2423px, bg #FFFFFF)
4. **section** — “Don't take our word for it” (1154px, bg #FFFFFF)
5. **section** — “Plug your calls into your agents” (1646px, bg #09090B)
6. **section** — “Liven up your working sessions” (1084px, bg #FAFAFA)
7. **section** — “Ready to get started?” (504px, bg #FFFFFF)
8. **footer** — “Tuple” (323px, bg #FFFFFF)

## Elevation & Depth

Style: subtle. Most used shadows:

- `rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`
- `rgba(0, 0, 0, 0.25) 0px 25px 50px -12px`
- `rgba(0, 0, 0, 0.1) 0px 1px 3px 0px, rgba(0, 0, 0, 0.1) 0px 1px 2px -1px`

## Shapes

Dominant corner radius is a full pill; radii in use: 6px, 8px, 12px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#6A5ED9`, textColor `#FFFFFF`, rounded `12px`, padding `16px 32px`, height `60px`, fontFamily `Inter`, fontSize `18px`, fontWeight `500` (e.g. “Download the app”)
- **button-secondary**: textColor `#27272A`, rounded `8px`, padding `7px 20px`, height `40px`, fontFamily `Inter`, fontSize `16px`, fontWeight `500`, border `1px solid #E4E4E7`, shadow `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px` (e.g. “Sign up”)
- **card**: rounded `12px`, padding `48px`, backgroundColor `#FFFFFF`, shadow `rgb(255, 255, 255) 0px 0px 0px 0px, rgba(0, 0, 0, 0.05) 0px 0px 0px 1px, rgba(0, 0, 0, 0.05) 0px 1px 2px 0px`

## Do's and Don'ts

- Do reserve `#6A5ED9` for primary actions and highlights; it covers only 0.36% of the painted page.
- Do set body copy in Inter at 16px / 1.625.
- Don't introduce font weights beyond 400, 500, 600.
- Do keep corners at pill 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.
