The purpose of these tasks is to reduce eye strain while watching mobile/laptop screen at night.

f.lux - windows
redshift - linux
cf.lumen - android (using since kitkat)
1. CF.Lumen or Inbuilt LiveDisplay (Settings > Display).
For this, configure CF.lumen in manual mode only.
Master Filter Mode: Disabled.
Notification mode: Never
Driver: Best Quality
This profile or task enable you to control different settings of LiveDisplay according as per your choice.
If you dont want to install CF.lumen then inbuilt LiveDisplay should also work, however I felt the CF.lumen root driver with Best Quality is great.
Feel free to change the task settings or extend as you like.
My daily use is to integrate these tasks in quick settings bar. Tasker has options to add some customize quick settings there.
