# Superlist — Design System

> dark, modern, medium, custom

Superlist stacks its promise in Haffer XH at 88px/600 — 'Tasks, notes, and plans. Finally in one app.' — white on deep ink #181824, with 16-18px body and flat zero-radius CTAs. Kinetic color blocks and app panels in the brand's red-coral cut through the dark; the Wunderlist lineage shows in how loudly it believes in lists.

## Colors

| Role | Value |
|------|-------|
| bg | `#181824` |
| surface | `#242430` |
| border | `#373742` |
| text | `#ECECEE` |
| text_muted | `#9B9BA1` |
| primary | `#0000EE` |
| accent | `#4F6BED` |
| link | `#4F6BED` |
| secondary | `#26253B` |
| button_bg | `#FFFFFF` |
| button_text | `#26253B` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `link` are all `#4F6BED` — one role, not several.
- **accent** `#4F6BED` — accent for emphasis — keep it rare on the page.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **secondary** `#26253B` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
