Create a custom theme in Presenton when you want future presentations to follow your brand colors, typography, and logo instead of the built-in theme styles. ## Before you start * Decide on your primary brand color and background color before you begin. * Keep your company name ready if you want it to appear in the theme. * Prepare your logo file and any custom font files if your brand uses them. Presenton builds a theme in four stages: **Brand**, **Palette**, **Fonts**, and **Logo**. You can review the live preview while moving through each step. ## Create a new theme ### Open the Themes area In the left navigation, click **Themes**. Presenton Slide Presentations page with the Themes option highlighted in the left sidebar On the Themes page, click **New Theme**.

Update any values that need adjustment.
