# Themes and appearance

> Change how 2Fin looks: Light, Dark or Match device, the glass theme with built-in backdrops or your own picture, and the grey Zen night theme. Themes never change your figures.

Open **Preferences → Appearance**. Every setting here applies to **this device only** and never changes your figures. On every plan.

## Mode

Choose **Light**, **Dark** or **Match device**.

![Preferences → Appearance](https://mintcdn.com/ai2fin/chVoLw4tztnwrMjl/images/screens/appearance-preferences-1280.webp?fit=max\&auto=format\&n=chVoLw4tztnwrMjl\&q=85\&s=1db88f1483423e08f869cccb5bed286d)

Preferences → Appearance. Example figures from test books.

## Themes

**1. Allow themes**

Turn on **Allow themes**. Off keeps 2Fin exactly as it is.

**2. Glass theme**

Turn on **Glass theme** for frosted panels over a backdrop, in light or dark. Pick a backdrop: Aurora, Dusk, Deep sea, Graphite and others.

**3. Your own picture**

Choose a picture of your own as the backdrop. It is scaled and kept in this browser on this device, and never uploaded. Delete it any time.

**4. Moving backdrop**

The backdrop drifts slowly. Turn off **Moving backdrop** to keep it still; it also rests when your system asks for reduced motion.

### Zen night

A grey night theme with no card borders and primary buttons in a slow teal-to-sea-blue gradient. Night only, and used instead of the glass theme.
