REDSHIFT(1)							   User Commands						       REDSHIFT(1)

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
