# Koto

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

Koto uses a dark canvas (#060606) with a monochrome palette. Type is set in **GT Kotoheim Condensed** (display), **GT Kotoheim**, **GT Kotoheim Mono** (mono), with 14px body text. Layout: fluid container, none-detected navigation, 4 sections. Built with next.js, tailwind, sanity, google-tag-manager, 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` | `#060606` | 0.122 0 0 | bg | 87.5% | `--color-black` |
| `surface` | `#141414` | 0.191 0 0 | surface | 6.3% | `--color-off-black` |
| `on-surface` | `#FFFFFF` | 1 0 0 | text | 1.8% | `--color-white` |
| `on-surface-variant` | `#989898` | 0.68 0 0 | muted | 1.7% | `--color-grey` |
| `color-5` | `#FFFFFF1A` (on bg `#1F1F1F`) | 1 0 39 | other | 2.5% | — |

Contrast: text on background 20.26:1, muted text 7.02:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **GT Kotoheim Condensed** (CSS: `gtKotoheimCondensed`) | display | 300 | 71.3% | webfont |
| **GT Kotoheim** (CSS: `gtKotoheim`) | body | 350 | 22.6% | webfont |
| **GT Kotoheim Mono** (CSS: `gtKotoheimMono`) | mono | 400 | 6.1% | webfont |

Scale (px): 11, 12, 14, 16, 38, 48. Effective ratio ≈ 1.508 (close to a perfect fifth). Body 14px at line-height 1.25; display 48px with tracking -0.01em. Headings are sentence case. On a 390px viewport the body is 13px and display 36px.

## Layout

Spacing follows a 4px base unit; the most used steps are 4, 6, 8, 12, 16, 24, 36, 48px. Sections open with about 282px of space before their first line of text. Content sits in a fluid container on a 16-column grid. Text density 0.023 (text area / page area).

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

1. **hero** — “We’re Koto” (2799px, bg #060606)
2. **section** (1688px, bg #060606)
3. **section** — “Koto acquires Stereo to build a new global studio network” (949px, bg #060606)
4. **section** — “Contact” (733px, bg #060606)

## Shapes

Dominant corner radius 0px; radii in use: 6px. 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 GT Kotoheim at 14px / 1.25.
- Do use GT Kotoheim Condensed only for display sizes, not for body text.
- Do tighten large headlines (-0.01em at 48px).
- Don't introduce font weights beyond 300, 350, 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 4px.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
