How it works

Set your wallpaper. Sconce does the rest.

Sconce reads your wallpaper

It measures the luminance of your current desktop wallpaper in real time from the menu bar.

It classifies light vs. dark

A configurable threshold determines whether your wallpaper is light or dark. Adjust the sensitivity to avoid flicker.

Your Mac switches automatically

macOS appearance changes to match. Change wallpapers, switch Spaces, rotate through a slideshow — Sconce follows along.

Seamless

Wallpaper in, appearance out

Every wallpaper change triggers a re-evaluation. No manual toggling, no shortcuts, no automations to maintain.
