Another Android 13 leak is on the way and this one is all about the design aspect. With Android 12, Google introduced its Material You theme engine (excluding Pixel), which uses a varied color palette across your home screen, widgets, icons and menus based on colors found in your wallpaper. It looks like this feature will be further enhanced in Android 13 (codenamed Tiramisu) as a new report from Android police describes new color palette combination options and brings us their source code names.
Tonal Spot, Expressive and Spritz theme settings (via: Android Police)
Tonal Spot, Vibrant, Expressive, Spritz each come with a preset of colors again based on the shades found in your wallpaper. The latter three options offer a wider choice of accent colors, some of which are not even part of the background palette. Spritz uses e.g. more muted monochromatic tones that go well with dark mode, while Expressive offers more popping colors that still match the core tones of your background image.
The new features are still in the early stages of development, and with at least a few more months ahead of the first Android 13 developer beta, we may see other changes take place.
