Overview

A theme bundles a color scheme, font scheme, and background style into one preset. Instead of configuring each visual element separately, set a single theme parameter and get a polished, cohesive presentation.

Theme vs. Manual Color + Font

If you set a theme and also set colorScheme or fontScheme, the explicit values override the theme defaults. This lets you start from a theme and customize selectively.

Choosing the Right Theme

• Minimal — Best for SaaS product decks and technical presentations. The dark background and clean Aptos font keep focus on content.
• Classic — Best for corporate settings, investor updates, and board presentations. Light background conveys professionalism.
• Dark — Best for product launches and keynotes. High contrast with Seaford font creates visual energy.
• Bold — Best for sales and marketing. Impact font and Burnt Orange colors demand attention.

Background Styles

Each theme sets a default background:

• Light backgrounds (light1) — white or near-white, professional, easy to print
• Dark backgrounds (dark1, dark2) — dark gray or black, modern, screen-optimized

The background style ensures text colors automatically adjust for readability.
