Material Design is the new design guideline by Google. Android (including Wear) is using it from version L and up, here's a watch face to go with it!
All colors are fully customizable right from the watch, just long press the watchface, click the small gear icon at the bottom of the screen and you'll be able to customize the watch face as you wish.
Feedback is welcome and appreciated, I will try to respond quickly.
Troubleshooting:
Sometimes it takes a little while to install new watch faces over a slow Bluetooth connection. Wait at least a few minutes after installing on phone, by then watch face should be installed on the watch as well. Try reinstalling or re-syncing all apps to the watch if it still fails. This unfortunately affects all third party watch faces on Android Wear.
