Is it a good idea to activate Redshift/flux all the day (not just at night)?

If it feels easier to look at your screen, do it. I have my daytime colour temperature a bit warmer than default on all my devices (then much warmer at night).

I'll go a step further: most screens even black has some brightness and blueness. You can see the difference if you wear blue-blocking glasses. A pair of those is worthwhile. They're more widespread and inexpensive these days.

But yeah, like the other reply, I use Redshift slightly less blue in daytime and much less blue at night.

What's your Redshift setting for daytime?

Do you or anyone else have a third setting for bedtime like f.lux has (say for 1 or 2 hours prior to bedtime)? If yes, how do you simulate this third setting and how do transition smoothly from the evening setting to the bedtime setting?

I set daytime to 6250. I try to remember to wear amber glasses at bedtime. And the KDE Plasma Redshift Control widget lets me quickly scroll over the icon to make things more red or less.

I don't have 3 different auto-settings. I would LIKE to do that though!! Is there a way to do that?

I use this in my .xinitrc, and keep redshift running all day. It automatically fades to red when the evening comes, and back again in the morning.

nice redshift -l <YOUR-LAT>:<YOUR-LON> -b 0.6 -t 5500:1900

Yes you can just run `redshift -O3400` (where 3400 is your colour temperature of choice) at startup and it'll switch to that temp, without fancy timing or latitude

How do you start Redshift on startup? I saw a suggestion about `redshift -O3400 &` in file `~/.xprofile`, and on this page someone mentions `.xinitrc`
