I am very new to Linux, so I apologize if my question is obvious to many people. I don't know if this is relevant, since I am still learning, but I am using the distro "pop! OS", which is built upon Ubuntu.
For Windows I use f.lux to tint my screen when it gets late, and when using Linux I have been using Redshift. My problem with Redshift however is that you are only able to specify when the red-shifting should begin, and you are not able to specify how quick the transition from normal colors, to the shifted colors will be. Does any alternative exist where you are able to specify both when the color shifting should begin, but also how quickly it will shift into the maximum specified tint?
