Google to release Android 12 Material You’s wallpaper theming system source code!

Android 12 monet

Just weeks away from the official release of Android 12, the new system will bring a new Material You design language, the most significant UI update since the release of Android 5.0 in 2014.

One of the main functions of Material You is the wallpaper-based theme engine “Monet”. According to information, the “Monet” theme system will be completely open-source with a follow-up update to Android 12.


The “Monet” theme system can automatically generate theme colors for the system based on the user’s wallpaper. According to Google, the color extraction engine uses clustering algorithms and material color targets to determine the primary and secondary colors of a user’s wallpaper.

A palette generation algorithm will create a rich hue of 5 colors (2 neutral colors and 3 accent colors) and 12 physical colors to determine the color closest to the user’s wallpaper. These color values ​​are stored in an index, and an application can use the API to call the index to theme its app’s UI.

Android 12 monet

When Google first launched its “Monet” theme system at the I/O developer’s conference earlier this year, it said the system would be carried over to the Pixel 6 series of mobile phones first. However, it did not say whether it would be open to other OEMs.

According to reports, a developer open-sourced his dynamic color palette generator similar to Google’s “monet”, which shows the AOSP algorithm for post-processing/filtering of extracted colors is reported “pretty close” to Google’s proprietary solution.

Well, it looks like the search engine giant is ready to release the source code of the algorithm, as two sources have confirmed that Google recently made a code change- “Add Monet to AOSP”. However, this patch was previously available in the internal beta of Android 13 but is now available for Android 12.1.

It is worth noting that the palette generation algorithm is an important part of the theming process and is expected to be open source in the upcoming Android 12.1 generation. As a reminder, the company has previously confirmed that a wallpaper-based theme system for the Pixel will be launching for the first time this fall.

On the other side, there is no information on how other OEMs like Samsung, Xiaomi, Oppo, Realme, and OnePlus will use this feature for their custom Android skins. Also, will Google bring Android 12.1 to non-Pixel phones, or is it still unique to the rumored Pixel Fold.
