As discussed in the previous post on configuring Lunar Calenders in Windows 10, another interesting feature was also introduced in the 15002 Windows 10 Build: Blue Light Settings. Recently more operating systems have included options for reducing the amount of blue light emitted after sundown. This is easier on your eyes and allows you to fall asleep better at night time.
There are a number of settings that can be configured in the Settings > Display > Blue light settings, settings menu. The settings that can be configured are as follows:
Because automation is a great thing and manually clicking through GUI interfaces is not always optimal I decided to write a PowerShell function to simplify the configuration. For example you could utilize this function to automatically disable the reduced blue light settings when color sensitive work is performed, or lower the amount of blue light emitted as the night progresses. These are some of the actions that the Set-BlueLight function can perform.
To instantly turn of the reduced blue light setting the following code can be run:
To enable the reduced color mode and set the color shift to Medium run the following code:
Set-BlueLight -EnableBlueLight -ColorTemperature MediumShift
To automatically reduce blue light emitted based on the Day and Night cycle in your geographical location execute this:
The values that are configured by the script are byte arrays in the registry, so it required a bit of reverse engineering to get the values to match the settings in the control panel. The function is currently available on GitHub in my Shared Scripts repository: Set-BlueLight
This function will be added to the CustomizeWindows10 module after I have developed my functional and unit tests to ensure the quality of this function.
