Customise Assistant Appearance

In Appearance, choose a preset colour or enter a custom colour, then select one identity style:

• Emoji;
• Icon; or
• Brand.

The preview is used on assistant cards, chat headers, and floating chat bubbles where supported. Choose an identity that is distinct from other assistants and remains understandable without relying on colour alone.

Appearance does not change the assistant's model, sources, permissions, or behaviour. Save the assistant and review it in both light and dark mode and at a narrow screen size.
