Control Windows 10/11's Night Light feature programmatically.
The binary format of the registry value was reverse engineered from
NightLight.cs
in the tiny-screen project
by Maclay74, and converted to Typescript with
help from ChatGPT.
For changing the scheduled Night Light settings via a slightly different registry key, see this post: https://superuser.com/a/1209192.
| Windows Version | Status |
|---|---|
| Windows 11 22H2 | ✅ Tested |
| Windows 10 21H2 | ❔ Untested but should work |
Please open an issue if you find that this package does not work on your version of Windows.
Since this works by modifying a single registry key, it can be done in any language. A few examples are implemented already.
