Themes for Home Assistant influenced by Material You by Google on Android.
This theme aims to match the styling of Material Design 3 (also known as Material You) apps like Google Home as closely as possible, so it may change over time as these apps evolve. It also aims to implement Material You redesigns of elements when possible.
Relies on card-mod for toolbar modifications, other Material You component redesigns, and Material You coloring. If you have card-mod installed and do not want these changes to apply, use the "No Mod" versions of this theme.
Don't like the blue accents? You can choose a different Material You base color! See below for more. Also requires card-mod.
This theme also includes "Transparent Card" versions with transparent card backgrounds. It also includes separate light and dark versions of all themes for niche use cases.
Light cards made using Big Slider Card.
This theme is super-charged by card-mod! Using card-mod many components have received Material You design upgrades.
Redesigns the toolbar and sidebar buttons to follow Material You navigation component guidelines.
- Retains the sidebar toggle and dashboard menu (small width screens) or action items (large width screens) from the navigation toolbar header in a top app bar.
- Non-view buttons appear at top of screen near their original locations.
- Buttons disappear when user is not scrolled to the top of the view.
- Converts the toolbar header view tabs bar into a navigation bar footer.
- Removes the default selection bar and ripple.
- Spaces the view icons evenly along the entire toolbar.
- WARNING: Subviews must be placed at the end of the toolbar for the view tab count to be correct, otherwise the view tabs will end up smaller than expected.
- While evenly spacing the icons should (and previously) be done by making their parent a flexbox, their parent is within a shadow-root which the view tabs are slotted into. Modifying this parent element with card-mod is possible but it is slow and inconsistent. A tab count and width calculation method is used instead, which is much faster and more consistent.
- Adds view names below the view icons.
- Highlights the current view with a colored icon and background behind the icon.
- Transition animation on view icon background when selected.
Desktop sidebar expanded and mobile.
- Icon and background of current view now uses primary and accent colors.
- Transition animation on view icon background when selected.
Desktop sidebar collapsed.
- Background of current view now uses primary and accent colors.
- Current view icon background is a circle to match Material You example of a navigation rail menu without labels.
- Track now encompasses thumb.
- Removes the default ripple in favor of a thumb that changes size when used.
- Uses primary and accent colors for the switch thumb and track.
- Adds a 40px margin to the top for the top app bar and an 80px margin to the bottom for the navigation bar.
- Adds a 12px margin to each side of the view to match the Google Home app.
- Add card button of classic lovelace views updated to better match the extended FAB specification.
If you do not want these changes, use the "No Mod" versions of the theme.
This theme supports Material You color theming! Create a helper template sensor named Material Rounded Base Color that returns the hex code of your preferred base color. The accent and primary color will be calculated using it, retaining your color's hue and saturation but altering it's luminance.
To create a template sensor helper:
- Navigate to
Settings>Devices & services>Helpers. - Click
+ CREATE HELPER. - Click
Template. - Click
Template a sensor. - Name the sensor
Material Rounded Base Color. The sensor entity ID should besensor.material_rounded_base_color. - Enter your Material You base color as a six digit hex code, like
238636or#db4437. You can also use a template to read a hex code from the state or attribute of a different entity, like{{ states("sensor.pixel_fold_accent_color") }}. - Click
SUBMIT.
You can also choose user specific colors by creating a sensor named Material Rounded Base Color Your Name, with your name being your person name as it appears on the Home Assistant people page. The sensory entity ID should be something like sensor.material_rounded_base_color_john_doe.
If you are using the Home Assistant Android companion app, you can enable the accent color sensor in the companion app settings to use your phone's Material You accent color as the theme base color:
- Navigate to
Settings>Companion app. - Click
Manage sensors. - Scroll down to the section titled
Dynamic colorand clickAccent color. - Toggle
Enable sensoron. It should now return your phone's Material You base color as a hex code.
NOTE: Card mod does not support all Home Assistant frontend elements like the developer tools and settings pages, and thew view configuration, add card, edit card configuration, and assist dialogues. These pages will still use the theme default colors on parts of the UI.

This theme was initially modified from Graphite theme, as it was my favorite Home Assistant theme on HACS before I created this one. Therefore, it may contain some legacy variables from it.
Due to the multiple versions and complexity of this theme, I have split it into multiple CSS and yaml files and created a Python git pre-commit build pipeline to compile all of the files into a single Home Assistant theme file. You can either run this build pipeline by making a git commit (not to the main repo of course) running the file build.sh, or running the pre-commit.py Python file.
Twelve versions of a theme are created per base theme - with card mod, without card mod, transparent cards with card mod, transparent cards without card mod, and a separate light and dark version of each. The no card mod versions of theme have the card-mod-theme fields removed and will have no design upgrades or custom colors. The separate light and dark versions of the theme are if you need to explicitly set a device to use light or dark mode without the Home Assistant built in theme mode options.
Any files under common that end in .yaml are treated as card-mod-*-yaml fields in the themes, and files ending in .css contain the actual card-mod CSS. Different overall version of the theme are included in separate folders, such as material_rounded. CSS files are copied into the card-mod yaml fields using jinja2 templates, allowing for repetitive styles that go in different shadow roots to all source from the same file.
The common folder also includes hex2hsl.jinja - a hex to HSL color formula ported to jinja2 for transforming user defined base colors into HSL. The HSL base color is used for calculating primary, accent, and other custom colors. How these custom colors are defined and used is determined at the theme folder level in user_colors.jinja. If possible, I would like to instead use Material You's HCT color system, but it would have to be ported to jinja2 along with a HCT to hex/rgb/hsl/etc function.
