# Themes & color schemes

> Pick the window theme, accent color, and terminal palette.

Rumus's appearance has three layers you can tune separately:

* **Window theme** — light, dark, acrylic, black gold, or follow the system.
* **Accent color** — the highlight tone used across the UI.
* **Terminal color scheme** — the palette your shell output uses.

Configure them all at **Settings → Appearance**.

## Window theme

Five options, picked from a row of swatches at the top of the Appearance settings page:

| Theme          | Notes                                                                                  |
| -------------- | -------------------------------------------------------------------------------------- |
| **Light**      | Standard light UI.                                                                     |
| **Dark**       | Standard dark UI.                                                                      |
| **Acrylic**    | Translucent dark UI with a frosted-glass effect. **Not supported on Linux X11**.       |
| **Black Gold** | A premium dark theme with gold accents. **Pro feature** — requires a Pro subscription. |
| **System**     | Tracks your OS's light / dark mode automatically.                                      |

### Acrylic opacity

When **Acrylic** is selected, an **Opacity** slider appears. Lower opacity lets more of the desktop show through; higher opacity is closer to a solid dark theme. Find what works for your setup — heavy desktop wallpapers usually want higher opacity, plain solid colors can take more transparency.

### Black Gold

A premium look intended for users who want the app to stand out. Subscribed Pro users see it in the swatch row; Free users see it greyed out with a Pro tag. See [Built-in models](/docs/models/built-in) for what Pro includes.

## Accent color

The accent color is the hue used for active state, focus rings, link underlines, and the few brand splashes around the UI. Twelve presets are available:

* **Default** (Rumus's signature blue-purple)
* **Blue**, **Sky Blue**, **Cyan**
* **Green**, **Lime**
* **Yellow**, **Orange**, **Red Orange**, **Red**
* **Rose**, **Pink Purple**

Pick from the swatch grid. The change applies instantly across the UI — no restart needed.

## Terminal color scheme

The window theme controls Rumus's chrome (the shell of the app). The **terminal color scheme** controls the palette your `ls`, `git`, `htop`, and friends use inside terminal tabs.

Rumus ships **two terminal palettes** that are linked to your window theme:

* **Dark scheme** — used when the window is in Dark, Acrylic, Black Gold, or System (dark) mode.
* **Light scheme** — used in Light or System (light) mode.

Each palette covers the standard 16 ANSI colors plus background, foreground, cursor, selection, and the bright variants — a total of around 18 swatches.

### Customize the palette

In **Settings → Appearance → Terminal colors**, expand the dark or light palette and click any swatch to change it. A color picker opens with hex input. Save to apply.

### Reset to defaults

Each palette has a **Reset to defaults** button that restores the shipping scheme.

## Choosing colors that work

* **Stick close to the standard ANSI hues.** Lots of CLI tools assume "red = error" and "green = success". A swapped palette breaks at-a-glance reading.
* **Test against the foreground.** Bright yellow on a near-black background is fine; bright yellow on light grey is invisible. Open a `git status` in a tab while you tweak so you can see the consequences immediately.
* **Mind the cursor and selection.** A selection color too close to the background eats your selection visibility; make sure both are clearly visible against your foreground text.

## Settings sync

Window theme, accent color, and the terminal palette are all part of [config sync](/docs/account/sync) — set them once, and your other devices pick them up.
