# Samuel Onuha Design System

## Overview

The interface is dark, built on **Near Black (#000000)** with **Cool Silver (#CACFD8)** text and almost no color: actions are carried by contrast, not hue.

Type is set in **Aspekta**. Headlines run large; body text is 16px. The surface language is flat. Controls are pill-shaped.

Measured from [samuelonuha.com](https://samuelonuha.com/) on November 7, 2026 at 1440×900 and 390×844 from 148 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 9 roles.

- **Near Black (#000000):** Page background, seen 1 time. Token `background`, CSS `--base-color-neutral--black`.
- **Cool Silver (#CACFD8):** Primary text and headings, seen 25 times. Token `on-surface`, CSS `--text-color--text-primary`.
- **White (#FFFFFF):** Headings and emphasis, seen 11 times. Token `on-surface-strong`, CSS `--background-color--background-alternate`.
- **Dark Blue (#525866):** Secondary text, seen 2 times. Token `on-surface-variant`, CSS `--base-color-brand--trout`.
- **Charcoal 81% (#222222CF):** Translucent fill for cards and controls, seen 1 time. Token `overlay`.
- **Graphite (#424344):** Borders and dividers, seen 9 times. Token `outline`.
- **White (#FFFFFF):** Primary buttons and calls to action, seen 35 times. Token `primary`, CSS `--background-color--background-alternate`.
- **Dark Blue (#525866):** Text and icons on primary. Token `on-primary`.
- **Indigo (#4D70FF):** Accent in text, fills and borders, seen 3 times. Token `secondary`.

## Typography

**Aspekta** carries the whole interface. Fallback stack: `Aspekta, sans-serif`. Other loaded fonts: Acme.

- **headline-display:** Aspekta 80px at weight 400, line height 1.2 (40px on mobile). Page title (h1).
- **headline-lg:** Aspekta 48px at weight 400, line height 1.2 (36px on mobile). Section headings (h2).
- **body-md:** Aspekta 16px at weight 400, line height 1.5. Body text.
- **body-lg:** Aspekta 18px at weight 400, line height 2.1. Lead paragraphs.
- **body-sm:** Aspekta 14px at weight 400, line height 1.5. Secondary and small text.

## Layout

Spacing is mostly on a 4px grid (74% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 16px, lg 24px, xl 64px.
- **Gaps:** 16px is the most common gap in flex and grid layouts.
- **Breakpoints:** 479px, 500px, 640px, 767px, 768px, 854px, 936px, 991px.

## Elevation & Depth

The design is flat: no shadows were measured. Hierarchy comes from color contrast and #424344 borders.

## Shapes

Interactive controls are pill-shaped. Measured radii, most used first:

- **full (9999px):** 28 elements.
- **md (12px):** 24 elements.
- **sm (2px):** 4 elements.
- **lg (99px):** 4 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“Learn More”):** #FFFFFF fill, #525866 text, 14px/400, 999px radius, padding 10px 24px, border 1px solid #000000.

## Do's and Don'ts

- Do use #000000 for the page.
- Do keep text in 3 levels: #CACFD8, #FFFFFF, #525866.
- Do let contrast carry emphasis; primary actions use #FFFFFF on #000000.
- Do reuse the measured spacing steps (8px, 16px, 24px).
- Do make buttons and chips fully rounded (9999px); most other elements use 12px corners.
- Don't use #525866 for body text; it reaches 2.95:1 on #000000. Keep it for large text or metadata.
- Don't add drop shadows for depth; use borders and contrast.
- Don't introduce new font families beyond Aspekta.
- Don't add saturated accent colors; the measured palette is almost entirely neutral.
- Don't make interface transitions slower than 0.375s.

## Motion

Interface transitions are quick: 0.375s, 0.3s, 0.2s.

- **Easing:** `ease`.
