# Spline

> Extracted from [https://spline.design/](https://spline.design/) 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

Spline uses a dark canvas (#000000) with a palette. Type is set in **Geist** (display + body), **Geist Mono** (mono), with 14px body text. Layout: 1320px container, top-sticky+blur navigation, 12 sections. Built with next.js, radix-ui, 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` | `#000000` | 0 0 0 | bg | 74.4% | `--color-bg` |
| `on-surface-variant` | `#8A8A8A` | 0.633 0 0 | muted | 2.2% | — |
| `on-surface` | `#EEEEEE` | 0.949 0 0 | text | 1.2% | — |
| `outline` | `#2E2E2E` | 0.301 0 0 | border | 0.06% | — |
| `color-5` | `#101010` | 0.173 0 0 | other | 12.9% | — |
| `white-090` | `#FFFFFFE6` (on bg `#E6E6E6`) | 1 0 0 | other | 3.5% | `--color-white-090` |
| `color-7` | `#1D1D1D` | 0.231 0 0 | other | 2.5% | — |
| `color-8` | `#000000D1` (on bg `#000000`) | 0 0 0 | other | 0.71% | — |
| `color-9` | `#3A3A3AB8` (on bg `#2A2A2A`) | 0.348 0 0 | other | 0.62% | — |
| `btn-bg-highlight` | `#FFFFFF0F` (on bg `#0F0F0F`) | 1 0 0 | other | 0.89% | `--color-btn-bg-highlight` |
| `color-11` | `#BDBDBD` | 0.798 0 0 | other | 0.30% | — |
| `color-12` | `#151515` | 0.196 0 0 | other | 0.40% | — |
| `color-13` | `#FFFFFF2E` (on bg `#2E2E2E`) | 1 0 0 | other | 0.09% | — |

Sparse chromatic highlights (not accents): `#8EB2F2`.

Declared brand/accent tokens: `--generate-accent` = `#1CC294` (declared, not painted on this page), `--generate-accent-solid` = `#00A376` (declared, not painted on this page).

Contrast: text on background 18.1:1, muted text 6.08:1, accent 18.1:1.

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

## Typography

| Family | Role | Weights | Share of text | Source |
|---|---|---|---|---|
| **Geist** | display, body | 400, 450, 500 | 94.2% | webfont |
| **Spline Sans** | other | 400, 500, 600 | 3.1% | webfont |
| **Geist Mono** | mono | 400 | 2.7% | webfont |

Declared in `@font-face` but not used to paint text on this page: Spline Sans Mono, Brockmann. Don't treat these as the page's fonts.

Scale (px): 11, 12, 12.5, 13, 14, 15, 16, 18, 20, 24, 48, 56. Effective ratio ≈ 1.219 (close to a minor third). Body 14px at line-height 1.429; display 48px with tracking -0.06em. Headings are sentence case. On a 390px viewport the body is 14px and display 36px.

## Layout

Spacing has no reliable single base unit; the most used steps are 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 14, 16, 20, 24px. Sections open with about 256px of space before their first line of text. Content sits in a 1320px container on a 2-column grid. Text density 0.078 (text area / page area).

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

1. **nav** (65px, bg #000000)
2. **section** (64px, bg #000000)
3. **hero** — “The tool for” (1434px, bg #000000)
4. **logos** (130px, bg #000000)
5. **section** — “From prompt to production in one file” (836px, bg #000000)
6. **section** — “Where ideas become production-ready experiences” (1050px, bg #000000)
7. **section** — “Everything you need for 3D design” (861px, bg #000000)
8. **section** — “Agents build. Designers refine.” (861px, bg #000000)
9. **section** — “One scene. Web, Apple and Android.” (1262px, bg #000000)
10. **testimonials** — “Why teams build with Spline” (751px, bg #000000)
11. **section** — “Start building in 3D” (668px, bg #000000)
12. **footer** (757px, bg #000000)

## Shapes

Dominant corner radius is a full pill; radii in use: 6px, 12px, 14px, 16px, pill. Borders: hairline (1px).

## Components

- **button-primary**: backgroundColor `#EEEEEE`, textColor `#000000`, rounded `9999px`, padding `0px 14px`, height `34px`, fontFamily `Geist`, fontSize `14px`, fontWeight `500`, border `1px solid #EEEEEE` (e.g. “Start building”)
- **button-secondary**: textColor `#EEEEEE`, rounded `9999px`, padding `0px 14px`, height `34px`, fontFamily `Geist`, fontSize `14px`, fontWeight `500`, border `1px solid #2E2E2E` (e.g. “Talk to sales”)
- **card**: rounded `16px`, padding `0px`, backgroundColor `#101010`

## Do's and Don'ts

- Do set body copy in Geist at 14px / 1.429.
- Do tighten large headlines (-0.06em at 48px).
- Don't introduce font weights beyond 400, 450, 500, 600.
- Don't add drop shadows; depth comes from tone and borders.
- Do keep corners at pill for most controls, and use the larger radii only for cards and media.
- Don't copy this site's logos, illustrations, photography or copy; use the system, not the brand assets.
