When theme customization, or theming, is used properly, it can help differentiate your Action. The choices you make when customizing the visual components of your Action (like basic cards, carousels, lists, etc.) will help you effectively convey your brand.
The Assistant’s design is constantly evolving to help users wherever they are, on whichever device they choose. So we’ve designed the guidelines in this section to evolve along with it. Our goal is to enable you to express your company’s identity in a way that 1) feels natural in the overall system interaction, 2) focuses on the biggest opportunities for brand expression, and 3) scales across all primary devices (for example, phones and smart displays) without additional work.
The default Assistant surface theme is applied to your Action visual component if you don’t specify theming details. You can go to the Actions Console to customize your Action theme.
