To create a custom theme, you have two options:

(1) You can edit an existing theme by clicking on the three dots at the bottom right of an existing theme, and selecting Customize this theme.

(2) Create a new theme by clicking on the new theme button under Themes.

When you opt to import a file to the theme editor, you're able to upload a PowerPoint or from Google Drive. Upload your file, and we'll create a Gamma theme using its colors, fonts, and logo.

You are able to build your own stunning theme in Gamma with our step-by-step builder. We will take you through 5 steps where you can choose your theme and background colors, your fonts, your design style, you can upload your logo, and of course, save your theme to be used as often as you'd like!

You can adapt the design of the cards, blocks and content, and buttons & links.

You can include specific keywords to be associated with your custom theme. These keywords will be appended to your prompts when generating AI images, in order to give your Ai images a consistent style. You can also add specific accent images for your custom theme.
