# Signal theme

Signal: Bricolage Grotesque headings over Figtree text, #ff5f1f for actions, buttons squared to 4px, 4px inputs and 7px cards. Flat: no shadows at all. Surfaces separate from the page by contrast alone.

Take it whole: `import 'rift-ds/tokens/presets/presets.css'` after the tokens, then set `data-brand="plum"` on `<html>`. See it at https://rift-ds.com/foundations/themes/plum.

## Colour

One action colour, kept for primary buttons, focus rings, the checked state of a control and the selected item of a set. Everything else is the neutral scale and five status roles. The logo wears the action colour (`logo`). Its mark is a gradient within that one colour (`logo-end`).

| Role | Light | Dark | Token |
| --- | --- | --- | --- |
| `primary` | `#ff5f1f` | `#ff5f1f` | `--color-action-primary-bg` |
| `primary-hover` | `#ff7b46` | `#ff7b46` | `--color-action-primary-bg-hover` |
| `primary-active` | `#ffa37f` | `#ffa37f` | `--color-action-primary-bg-active` |
| `on-primary` | `#060c17` | `#060c17` | `--color-action-primary-text` |
| `canvas-light` | `#eef1f6` | `#090b0e` | `--color-bg-page-primary` |
| `surface` | `#ffffff` | `rgba(17, 19, 23, 0.8)` | `--color-bg-container-primary` |
| `surface-soft` | `#eef1f6` | `#313336` | `--color-bg-container-secondary` |
| `ink` | `#090c10` | `#e4e6ea` | `--color-text-primary` |
| `display` | `#0f1e37` | `#c9daf5` | `--color-text-display` |
| `heading` | `#090c10` | `#e4e6ea` | `--color-text-heading` |

| `logo-end` | `#ffa37f` | `#ffa37f` | `--color-brand-mark-end` |
| `text-secondary` | `#313337` | `#b3b5b9` | `--color-text-secondary` |
| `text-tertiary` | `#696b6f` | `#9b9da0` | `--color-text-tertiary` |
| `border` | `#caccd0` | `#25272a` | `--color-bg-container-border` |
| `input` | `#ffffff` | `#090b0e` | `--color-input-bg-primary` |
| `error` | `#b4313d` | `#de5764` | `--color-status-error-icon` |
| `success` | `#247b55` | `#2e9e6e` | `--color-status-positive-icon` |
| `warning` | `#c14817` | `#ff5f1f` | `--color-status-warning-icon` |
| `info` | `#4e85e3` | `#719ce8` | `--color-status-info-icon` |

Accents, for charts and the background field: amber `#1e9e8a`, cobalt `#5cc8e8`, coral `#ffb37a`, gold `#8fb8f0`, mint `#2f6fde`, violet `#1f4fa0`.

## Typography

Bricolage Grotesque headings over Figtree text. Levels inside a tier share a weight and step by size. Display type `display` takes its own colour, while running text stays in the ink.

| Style | Face | Size | Weight | Line height | Tracking |
| --- | --- | --- | --- | --- | --- |
| `display-lg` | Bricolage Grotesque | 96px | 500 | 1.05 | -0.022em |
| `display-md` | Bricolage Grotesque | 64px | 500 | 1.1 | -0.018em |
| `sub-display` | Bricolage Grotesque | 30px | 500 | 44px | -0.012em |
| `heading-1` | Bricolage Grotesque | 30px | 500 | 44px | 0.025em |
| `heading-2` | Bricolage Grotesque | 26px | 500 | 32px | 0.025em |
| `heading-3` | Bricolage Grotesque | 22px | 500 | 28px | 0.025em |
| `title` | Figtree | 16px | 500 | 24px | 0 |
| `body-md` | Figtree | 16px | 400 | 24px | 0.01em |

| `overline` | Figtree | 14px | 600 | 20px | 0.09em |
