redshift

Adjust the color temperature of your screen according to your surroundings. More information: http://jonls.dk/redshift.

• 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}}

• Turn on Redshift with a constant unchanging color temperature:

redshift -O {{temperature}}
