Dim

Dim screen below device minimum and add any coloured filter over device's screen

This app enables a user to dim his device's screen below the minimum by applying a black filter over the entire screen. It also enables one to use a red filter that filters excess blue light for more comfortable use of your device at night. One can also apply a custom filter of any colour by combining various shades of red, green and blue. A widget is provided for quick on/off toggling of the most recently applied filter.
