Sundown for Mac

Sundown for Mac lives in the menu bar and looks after the colour warmth of your display. You set the times once, and each evening the screen moves to warmer tones at sunset without you having to touch anything. Warmth runs on a Kelvin ladder from 6500K, ordinary daylight white, down to 500K, a deep red, in steps of 100K, so you choose exactly how warm the evening gets. It needs macOS 14 or later, and the Classic build covers macOS 12 and 13. It is a paid app with a 7-day trial. Made by Jack Richards.
