# Supporting Dark Mode

> Guide on how to provide ad creatives that match your app's Dark Mode.

## What is Dark Mode?

Dark Mode is a UI theme that uses bright text on a dark background. When the app is in Dark Mode, displaying ads with dark-toned creatives improves user experience.

Enabling the Dark Mode creative feature allows you to operate ads optimized for both light mode and Dark Mode environments with a single Ad Unit.

</Warning>

## Configuration Method

Enable the **Receive Dark Mode Creatives** toggle when creating or modifying an Ad Unit.

| Setting | Behavior                                      |
| ------- | --------------------------------------------- |
| **ON**  | Can receive Dark Mode creatives               |
| **OFF** | Always receive only default (light) creatives |

***

## How It Works

1. **Ad Unit Setting**: Enable receiving Dark Mode creatives in the Ad Unit.
2. **Creative Registration**: Advertisers register both light mode and Dark Mode creatives when booking campaigns.
3. **SDK Request**: The SDK automatically detects the app's current theme (light/dark) and makes requests.
4. **Creative Response**: Returns Dark Mode creative when Dark Mode is requested.

### Fallback Behavior

If no Dark Mode creative is registered, light mode creative is displayed.

## Cautions

**Changing Settings During Campaign**

If you enable Dark Mode for an Ad Unit included in a running campaign, light mode creative is displayed as the default.

**Creative Review**

Light mode and Dark Mode creatives are reviewed simultaneously. If either violates policy, the entire creative set is rejected.
