Does the chat widget support dark mode?

Yes. Choose light, dark, or automatic appearance in the Shopify theme editor's Simple Chat settings.

Automatic matches the storefront's appearance. A light store keeps a light widget even if the customer's device uses dark mode. If the storefront switches to dark, the widget can follow it.

1. Open Online Store > Themes > Customize.
2. Select the Simple Chat app block.
3. Choose the appearance option.
4. Check the preview and save.

Test the message bubbles and buttons against your brand colors on mobile and desktop. The assistant's name and avatar are managed separately in Branding.
