# Appearance

> Make O comfortable to read and use.

Choose a light or dark appearance, try a color theme, and adjust the font size. You can also choose how side panels behave and whether to show a daily quote.

## Where to find it

Open Settings from the user/application menu and choose Appearance.

## What you can do

* Choose Light, Dark, or System.
* Choose a visual style and filter color themes by category.
* Adjust font size with the slider.
* Set Dock and Daily Quote preferences; use Reset to restore defaults.

## How to use it

* Try one change at a time and see how it looks in the preview or on the page.
* Use the color theme category buttons (All, Minimal, Colorful, Branded, Creative, Dark) to find a theme.
* Unpin on Close is experimental: closing a pinned side-panel tab moves it into a floating window. This does not apply to the Assistant.

<Note>
  **Availability and privacy.** Theme choices depend on the current application options. Appearance changes do not change workspace data.
