On Windows I have an "Intel HD Graphics Control Panel" that allows me to change the screen's color settings (brightness, contrast, hue, saturation etc.) I was looking for a similar tool on Ubuntu but could not find anything. Is there something similar available on Linux?

I am using Ubuntu 19.04 at the moment.

Have you looked at this doc:
https://help.ubuntu.com/stable/ubunt...screen.html.en

If you are using the Gnome desktop, this may also help: https://help.gnome.org/users/gnome-h...isplay.html.en

With the amd proprietary driver there's amdcccle. With the nvidia ones, something like nvidia-xconfig (don't have one, can't be bothered to verify if it's +/-x). Otherwise there's xrandr.

$ xrandr --output HDMI-A-0 --brightness 0.99 --gamma 1.35:1.35:1.35

Where the numbers are float values (default = 1.0). And the multiple values are in Red:Green:Blue order. Sometimes there's desktop interfaces for these. And libxca used to be one that could take configuration files from calibration hardware that worked in windows. Things like xbacklight and other ways to fiddle depending on the hardware.

Depends on how you define change color?

$ xsetroot -solid Blue4

$ xsetroot -solid rgb:00/33/00

Where the rgb numbers are hex and in Red/Green/Blue order. Blue4 being a built in one close to the blue screen of death. For those times you feel life might be simpler in windows, refresh your memory of your dysfunctional past.
