Adjust the color temperature of a screen according to its surroundings. Note: Redshift does not support Wayland.
Turn on Redshift with temperature set to 5700k during the day and 3600k at night
redshift -t 5700:3600IdentifyTurn on Redshift with a manually specified custom location
redshift -l latitude:longitudeIdentifyTurn on Redshift with screen brightness set to 70% during the day and 40% at night
redshift -b 0.7:0.4IdentifyTurn on Redshift with custom gamma levels (between 0 and 1)
redshift -g red:green:blueIdentifyPurge existing temperature changes and set a constant unchanging color temperature in One-shot mode
