What is a custom theme?

In Gamma, themes determine the visual style of your presentation, document, or webpage, including the colors, fonts, card styles, and accent images.

Pro tip: Custom themes are automatically shared with the users in your workspace.

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.

How do I import a theme?

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.

How do I build a new theme?

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!

How do I edit an existing theme?

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.

From here, you'll be taken to the theme editor where you can adjust your:

How do I use my own colors?

You can modify a theme to use your own color palette. First, click edit theme, then navigate to Colors. From there you will be able to customize the colors used in elements like links, buttons, and backgrounds. Either enter the Hex code you want to use or click the colored box to open the color wheel.

If you want to customize font colors, click Fonts and you can change the color of headings and body text. You can even use gradients!

Fonts and typography settings

In custom themes, you now have more control over your typography! We've added controls for:

  1. Line height

  2. Letter spacing

  3. Base size

  4. Uppercasing (headings only)

These can be helpful if the eg. font you're using runs a little small and needs to be scaled up, or the default line height and letter spacing doesn't align with your brand guidelines.

How can I use my logo?

You can use your own logo in Gamma by going to Themes > Edit Theme > Logo. Import your logo and you'll see it appear in the bottom left corner of all decks using that theme!

How can I adjust the design?

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

  • Roundness: how round or sharp your cards and content are

  • Stroke and shadow: you can now have outlined or hard-shadowed cards

  • Block colors and fill: more precise control over the colors of your smart layouts and other elements

How can I set a consistent image style?

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.
