If you are a Google Gboard app, we have a small tip for you. The latest beta of this app from Google, specifically version 7.8.8, added a few new key themes for enthusiasts to enjoy.
New themes are divided into two categories: Light Gradient and Dark Gradient (light and dark transitions, note red).
All topics are represented by multiple color transitions. There are 25 light variants and 29 dark colors.
In the pictures, you can see the selection of colors and their use on the keyboard. According to xda-developers, the themes are available on Google Pixel 3 and Pixel 3XL. However, Huawei Mate 20 X was not found (unlike Huawei Mate 20 Pro, where yes !).
So it looks like functionality is not limited to Google devices only. The most trusted test is to try and try out the latest beta version of the Google Play Store.
