When I was starting B6H5, I had Claude Code generate wallpapers that I could use on my Mac that utilized the company logo and the accent colors on the website. The wallpapers are a fun silly thing that remind me every time I see them that I have something to focus on for myself. The website offers a light and dark theme and so Claude generated wallpapers that match, white background for light theme and black background for dark theme. Then I set the generated wallpapers to rotate…

I am a huge fan of dark themed user interfaces or so I thought. While the wallpapers were rotating I started to gain an appreciation for light themed user interfaces. I am not sure whether I really liked the light themed interface though or if I had been in dark theme for too long or whether it was the contrast between the macOS user interface elements and the light wallpapers that caught my attention. Whatever it was, it made me question whether or not the theme on macOS could be set based on the wallpaper currently in use.

And that is how Sconce was born. Sconce is a macOS menu bar application that watches the wallpaper of your Mac and decides what macOS theme should be set based on your preferences, match the brightness/luminance of the wallpaper or the inverse if you want more contrast in your user interface. Sconce does not store any recordings of your screen, Sconce only operates locally and does not “phone home” any information about what you select.

I have been running Sconce locally with my wallpapers set to change every 15 minutes for the last month and I still am unsure what configuration I like the best – match the brightness/luminance of the wallpaper or have the inverse. Either way, it has brought me some enjoyment over seeing the macOS theme transition automatically when the wallpaper changes and I hope you enjoy it as well.

Check out Sconce while it is free during its beta period and if you enjoy it enough, come back and purchase a license once there is a paid version.
