[SWITCH] Fizeau v1.4.1 released

 AUG 12, 2020

The developer averne has released a new homebrew for Nintendo Switch called Fizeu with the new version 1.4.1 that adds support for 10.x firmware.Fizeau allows you to change the brightness of the screen (like reading mode on smartphones), the color or create a color level on your Nintendo Switch.


  • Create a layer of which color you can adjust.
  • Preset values ​​for color temperature (f.lux / redshift-like).
  • Check the brightness of the screen.
  • Save sunrise / sunset times and screen brightness and automatically apply settings.


How to use it

Temperature / Color:

  • Use the temperature slider to select the desired shade.
  • You can override the color using the RGBA sliders.
  • The “Alpha” value controls the opacity of the layer.
  • Due to the way Fizeau works, it is unfortunately not possible to change the screen color directly. Instead, create a transparent layer and apply color to it. However, this can result in an overall increase in brightness, which is especially noticeable in dark colors.
  • Also, the layer is not visible in screenshots / recordings.


  • Use the brightness slider to set the desired screen brightness.
  • This is not redundant with the built-in setting, as the value will be set at dusk.

Sunrise / sunset:

  • When set, Fizeau will start at “twilight” time and shut off at “sunrise” time.
  • You can ignore it using the checkbox. Fizeau will then remain in the specified state.


  • The settings are saved to /switch/Fizeau/config.ini, which you can also change.
  • To reduce memory usage of the sysmodule, the settings are not read continuously. Instead, they are applied when the application starts.
  • Therefore, you will have to restart the client after a reboot to restart Fizeau.


  • Download the  latest version  , unzip it to the root of your SD card and reboot.
  • Only the latest version of Atmosphère  CFW is supported  .
