Apple included some new versions of their Pride watch face in watchOS 6.2.5, and I had to take the opportunity to make a few wallpapers using the color scheme and design of these new faces. We're still a few weeks from official Pride month, but I figured you'd be okay having them a little early.
There are a bunch here, so hopefully you'll find something that works for you.
Note that these are meant to replicate the existing stripe wallapeprs in iOS/iPadOS. They just happen to use the same colors as the Pride watch faces.
