Hello,
Actually I'm using the Clarity Activity alternate
https://apps.garmin.com/en-US/apps/703e3d9a-8823-4118-ad4c-a8b263bfed14
And with that I've discovered you can program the watchface to have diferent backgroud and colors at day and "aftersunset"
But that one puts black-night and white-day
I suggested the creator to do it the oposite, in order to enhace fenix 3 bad visibility at low light conditions
And also I think it would be a good idea to have "alternate" versions in all your watchfaces creations
regards
