Document theme colours
A theme is a set of colour tokens and two fonts, and every block on the page reads from it. Switching theme restyles the headings, the tables, the charts and the callouts together rather than one at a time.
Ten themes, chosen by register
Slate, Navy, Forest, Terracotta, Plum, Ocean, Sand, Graphite, Midnight and Amber Noir. They are not interchangeable. A legal document wants Slate, Navy or Midnight, because a contract read in a dispute should look sober. A corporate report suits Navy, Slate, Ocean or Forest. Editorial work, a case study or a brochure, can carry Terracotta, Plum, Sand or one of the dark presets.
Everything reads from the same tokens
A theme sets a background, a foreground, a muted surface, a card surface, a primary, a secondary and a tertiary colour, the text colours that sit on each of those, a border, and the heading and body fonts. Charts, tables, callouts and section bands all draw from that set, which is why a theme change never leaves one block in the old colours.
Describe a look and get a theme
Above the theme list there is a box that takes a sentence, something like a warm and confident law firm with deep burgundy on ivory and serif headings, and generates a theme from it. It is the fastest way to get close to a brand you cannot name a hex code for, and the result is editable afterwards on the colours and fonts tabs.
Light and dark are not decoration
The dark presets keep their muted and card surfaces lighter than the background, and the light ones keep them near white. That relationship is what stops a dark theme turning a table into an unreadable block. If you edit colours by hand, keep it: a dark theme with a darker card is the fastest way to break a document.
How it works, in three steps
Step 1
Pick by register, not by favourite
Sober themes for legal and corporate, expressive ones for editorial work.
Step 2
Or describe the look
A sentence about the brand generates a theme you can then edit.
Step 3
Check a table and a callout
Those two show up a bad colour relationship faster than a page of text does.

Limits worth knowing
- Ten built-in document themes.
- A theme applies to the whole document, not per section.
- Charts and blocks take theme colours, so they cannot be coloured independently.

Questions people ask
How many document themes are there?
Ten built in, plus any you generate from a description or build yourself on the colours and fonts tabs.
Can I match my brand exactly?
Yes. Describe the look to get close, then edit the colours and fonts directly.
Does changing the theme change my content?
No. It changes colours and fonts. The words, blocks and page breaks stay as they are.

Form themes and colours
A theme restyles the whole form at once: background, form surface, input borders, focus colour, buttons and type. There are 12 for classic forms and 25 for conversational ones, and you can change your mind after every one of them.
Custom document theme
When none of the ten presets is your brand, you have two routes: describe the look in a sentence and let it generate one, or set the colour tokens yourself. Most people should start with the first.
Flyer colour themes
A theme is not a background colour. It is a palette, a type scale and a set of geometry rules that every element on the flyer reads from, which is why choosing a different one repaints the headline, the panels, the icons, the chart series and the borders in one move rather than one box at a time.
