redshift

all

Adjust the color temperature of a screen according to its surroundings. Note: Redshift does not support Wayland.

Examples (5)

Turn on Redshift with a specific [t]emperature during day (e.g., 5700K) and at night (e.g., 3600K)

redshift -t 5700:3600

Turn on Redshift with a manually specified custom [l]ocation

redshift -l latitude:longitude

Turn on Redshift with a specific screen [b]rightness during the day (e.g, 70%) and at night (e.g., 40%)

redshift -b 0.7:0.4

Turn on Redshift with custom [g]amma levels (between 0 and 1)

redshift -g red:green:blue

[P]urge existing temperature changes and set a constant unchanging color temperature in [O]ne-shot mode

redshift -PO temperature
