Is there a night light mode for AMD/Radeon, Intel & Nvidia graphics drivers?

Is there a night light mode on FreeBSD for AMD/Radeon, Intel & Nvidia graphics drivers, that can be turned on?

It's to turn down blue light, so to not disrupt sleeping patterns.

Also, should I use orange text on a black background for reading text on screen, in relation to night light settings?

I am using "redshift" on X11/awesome, which seems to work

$ [~/.config/redshift] cat redshift.conf
[redshift]
temp-day=6500
temp-night=4000
fade=1
brightness-day=1.0
brightness-night=0.9

[manual]
lat=your lat
lon=your lon

$ [~/.config/awesome] cat rc.lua | grep -i -A1 -B1 redshift
awful.spawn.with_shell(
  "pgrep redshift >/dev/null || redshift -c $HOME/.config/redshift/redshift.conf -l manual -m randr"
)

you may auto-run the above command in quotes in your own wm at start up.

accessibility/redshift has been mentioned,

I couldn't get redshift properly configured, I find accessibility/gammy more user friendly. It has also "auto brightness" and "auto temperature" adjusting according to the timezone (I guess), or both can be adjusted manually. It can attach itself to the notification area of a panel. [1]

Currently the port is removed from the ports tree, marked "BROKEN Abandoned and unfetchable", unfetchabel because the github account https://github.com/Fushko does not exist anymore, but there is a forked repository (forked from a 3rd party).

If the port has been adjusted accordingly, it can be compiled without any problems:

accessibility/gammy/Makefile

- BROKEN=                Abandoned and unfetchable
- GH_ACCOUNT=     Fushko
+ GH_ACCOUNT=     fasevd33

accessibility/gammy # make makesum
