# How to switch between the light and dark themes

This guide shows how to change Ori's colour theme. It assumes Ori is open in your browser (see the [getting started tutorial](../tutorials/getting-started.md)).

## Steps

1. Look at the right of the header, next to **⊞ Workspace**: the **☾** button switches to the dark theme; once dark, it becomes **☀** and switches back to light.
2. Click it. The whole page follows — conversation, workspace panel, code previews and editor (Monaco switches between its `light` and `vs-dark` palettes).

## Variants

- Light is the default. Ori no longer follows the operating system's light/dark preference: the theme is whatever was chosen last in this browser.
- The choice is remembered per browser (localStorage key `ori.theme`, values `light` or `dark`) and applied before the first paint on the next load. Clearing the site data restores light.
- The terminal tab keeps a dark background in both themes, like an IDE's integrated terminal.
- Several browsers connected to the same Ori server each keep their own theme: it is a browser preference, not part of the shared session.
