NAME

       gtk-redshift - Set color temperature of display according to time of day (gtk-Frontend).

SYNOPSIS

       redshift -l LAT:LON -t DAY:NIGHT [OPTIONS...]

DESCRIPTION

       Redshift adjusts the color temperature of your screen according to your surroundings. This
       may help your eyes hurt less if you are working in front of the screen at night.

       -h     Display this help message

       -v     Verbose output

       -V     Show program version

       -b N   Screen brightness to apply (max is 1.0)

       -c FILE
              Load settings from specified configuration file

       -g R:G:B
              Additional gamma correction to apply

       -l LAT:LON
              Your current location

       -l PROVIDER
              Select provider for automatic  location  updates  (Type  `list'  to  see  available
              providers)

       -m METHOD
              Method to use to set color temperature (Type `list' to see available methods)

       -o     One shot mode (do not continuously adjust color temperature)

       -O TEMP
              One shot manual mode (set color temperature)

       -x     Reset mode (remove adjustment from screen)

       -r     Disable temperature transitions

       -t DAY:NIGHT
              Color temperature to set at daytime/night

       The  neutral  temperature is 6500K. Using this value will not change the color temperature
       of the display. Setting the color temperature to a value higher than this results in  more
       blue light, and setting a lower value will result in more red light.

       Default values:

              Daytime temperature: 5500K Night temperature: 3700K
