This call provides the three most common hues from a wallpaper, which are generated by [WallpaperManager] upon setting of the lock and/or system (home) screen. The three colors; primary, secondary and tertiary, are set by a variational K-means quantifier and provided to applications with the [getWallpaperColors()] call. As introduced in the Material You update (Android 12 and up), this information is meant to be used to match application and system themes to the theme of the wallpaper. However, the information on these three hues are excellent for fingerprinting, as there is a great diversity of wallpapers. -![An image of the Fingerprint Application](https://raw.githubusercontent.com/ColoursofOSINT/ColoursofOSINT.github.io/master/assets/img/images/fingerprint/Fingerprint2.png) _An image of the Fingerprint Application_ +![An image of the Fingerprint Application](https://raw.githubusercontent.com/ColoursofOSINT/ColoursofOSINT.github.io/master/assets/img/images/fingerprint/Fingerprint1.png) +![An image of the Fingerprint Application](https://raw.githubusercontent.com/ColoursofOSINT/ColoursofOSINT.github.io/master/assets/img/images/fingerprint/Fingerprint2.png) +_An image of the Fingerprint Application_ # The Math For each of the three most common hues, there are 256 combinations for each RGB value, for a total of 2^24 combinations per color.
