Google is rolling out the dark mode to Google Play Store app in many regions.
The Google Play Store dark theme recognizes Android 10’s system-level setting. There are reports (via Reddit) of the dark theme enabled with Play Store 16.7.21, which is rolling out right now.
Dark Mode includes the main feed, navigation drawer, and bottom bar, while the search bar uses a lighter shade. This is especially true of the light green when dealing with apps and their Play Store listings, as well as Play Pass.
