Change your presentation's theme, fonts and colours

This guide shows you how to restyle a presentation: swap the whole deck’s colours and fonts in one click, change how a single slide is coloured, and put a background pattern behind it.

The point of a theme is that you never recolour anything by hand. Every colour on a slide points at the theme, so changing the theme changes all of them at once, and nothing needs cleaning up afterwards.

Open the Theme panel

Click Theme in the top bar of the builder. A panel opens on the right with two tabs, Themes and Fonts, under the line “Updates every color and font. No content is lost.”

The Theme button lives in the top bar. Themes and Fonts are two tabs in one panel.

Pick a theme

There are 99 themes in the list, split into two groups: Top picks, the 42 we recommend starting from, and More palettes below it.

Each row shows a strip of seven colours, the theme’s name, and its id underneath. Judge on the strip rather than the name, because the strip is literally the palette the deck will wear: the heading colour, the accent, the card colours behind your points.

Click one and the whole presentation restyles immediately. Every slide, every chart, every table header, every diagram. There is no “apply to all” step and nothing to fix afterwards.

Ninety-nine palettes. The tick marks the one your deck is wearing.

Try a few. Swapping is free and instant, and there’s no penalty for changing your mind on slide 20.

Set the font for the whole deck

Switch to the Fonts tab. The first row is Theme default, followed by the name of the font your current theme uses. Under it are 27 fonts, each rendered in its own typeface so you can read it before you pick it: sans faces like Inter, Montserrat, Poppins, DM Sans and Space Grotesk, and serif faces like Playfair Display, Merriweather, Lora and Cormorant Garamond.

Picking one sets it for the entire presentation and overrides whatever the theme brought with it. Picking Theme default hands control back to the theme, so a later theme swap changes the font again.

Each row is set in its own font. Pick one for the deck, or leave it to the theme.

Need one heading in a different face rather than the whole deck? That’s a per-text setting in the inspector, covered in style text and add callouts, stats and lists.

Four colour looks, one per slide

Look at the top-right corner of the slide on the canvas. The small round button there is Change color mode, and it cycles the current slide through four ways of using the same palette:

• Spectrum — cards and blocks each take a different colour from the palette. The liveliest look, good for agendas, pillars and feature grids.
• Matching — everything uses the one brand colour. Calm and corporate.
• Outline — cards become outlines instead of fills, so the slide breathes. Good when a slide is dense.
• Dark — the slide flips to a dark surface with light text. Good for covers, section dividers and closings.

It applies to the slide you’re on, not the deck, so a dark cover in front of light content slides is a normal thing to do. The button tints itself whenever the slide is on anything other than spectrum, so you can see at a glance which slides you’ve changed.

One button, four looks, and it only touches the slide you’re on.

Every template is built to work in all four, so you can cycle a slide without checking whether the text is still readable. Charts are the deliberate exception: they keep their multi-colour series in every mode, because flattening a chart to one colour makes it unreadable.

Put a background behind a slide

Backgrounds are the last section in the inspector on the right, under the heading Background. Click the row and you get None plus 15 patterns grouped by kind:

Group	Patterns
Geometric	Quarter Circle, Corner Triangle, Split Diagonal, Floating Squares, Editorial Pipes, Editorial Pipes (Bottom Left)
Organic	Bokeh, Corner Rings, Editorial Circles, Soft Spotlight, Gradient Mesh, Top Curve, Bottom Wave
Accent	Left Panel, Subtle Line

Each option previews as a small live tile in your theme’s colours, so you see the real thing rather than a generic swatch. Like colour mode, a background belongs to one slide, which is how you make a cover or a section divider stand apart without touching the rest of the deck.

Fifteen patterns, previewed in your own theme colours.

What’s deck-wide and what’s per slide

Setting	Where	Scope
Theme	Top bar → Theme → Themes	Whole deck
Font	Top bar → Theme → Fonts	Whole deck
Colour mode	Button on the slide corner	One slide
Background	Inspector → Background	One slide
Font, colour, size of one text box	Inspector, with the text selected	One element

You can also just ask. Open the AI assistant and say “swap to a darker theme” and it does the same swap, described in edit your deck with the AI assistant.
