With __2__ (color schemes) __x 21__ (primary colors) __x 17__ (accent color)
= __714__ combinations, it's impossible to ensure that all configurations
provide a good user experience (e.g. _yellow on light background_). Make
sure that the color combination of your choosing provides enough contrast
and tweak CSS variables where necessary.
### Color palette toggle
It's also possible to add multiple color palettes, including a [scheme][8],
[primary][9] and [accent][10] color each, and let the user choose. A color
palette toggle can be added via `mkdocs.yml`:
[:octicons-file-code-24: Source][6] · :octicons-milestone-24: Default: _none_
``` yaml
It's also possible to offer a list of color palettes to the user, each of which
can include a [`scheme`][7], [`primary`][8] and [`accent`][9] color each. The
user can toggle between those color palettes:
``` yaml hl_lines="4-6 8-10"
theme:
palette:
# Light mode
- media: "(prefers-color-scheme: light)"
scheme: default
primary: indigo
accent: indigo
- scheme: default
toggle:
icon: material/toggle-switch-off-outline
name: Switch to dark mode
# Dark mode
- media: "(prefers-color-scheme: dark)"
scheme: slate
primary: blue
accent: blue
- scheme: slate
toggle:
icon: material/toggle-switch
name: Switch to light mode
```
In order to set a default theme based on user preference, add a valid media
query to the `media` attribute. This will render a color palette toggle in the
header next to the search bar:
<figure markdown="1">
=== "Light mode"
[![Light mode][11]][11]
=== "Dark mode"
[![Dark mode][12]][12]
<figcaption markdown="1" style="margin-top: -2.0rem">
A demo is worth a thousand words — check it out at
[squidfunk.github.io/mkdocs-material-insiders][7]
</figcaption>
</figure>
The `toggle` field allows to specify an `icon` and `name` for each palette. The
toggle is rendered next to the search bar and will cycle through all defined
color palettes:
The following fields must be set for each toggle:
`icon`{ #icon }

### System preference
[:octicons-file-code-24: Source][6] · :octicons-milestone-24: Default: _none_
In order to automatically set the color palette to the user's system preference,
a media query can be set as part of the `media` field next to the toggle
definition in `mkdocs.yml`:
``` yaml hl_lines="3 8"
theme:
palette:
- media: "(prefers-color-scheme: light)"
scheme: default
toggle:
icon: material/toggle-switch-off-outline
name: Switch to dark mode
- media: "(prefers-color-scheme: dark)"
scheme: slate
toggle:
icon: material/toggle-switch
name: Switch to light mode
```
When the user first visits your site, the media queries are evaluated in the
order of their definition. The first media query that matches selects the
default color palette.
