How to change colors that are too white in Ubuntu 18.04?

Question

ubuntu

Installed Ubuntu 18.04 and noticed that the colors are too white.
I tried to fix it:
xgamma -rgamma 0.8 -ggamma 0.8 -bgamma 0.8
in google docs becomes normal, but in PyCharm the text becomes hard to see (especially in a dark theme).
tried:
sudo redshift -r -t 5700:3500
a little better, but very yellow
tried to combine: sudo redshift -r
-t 5700:3500 -g 0.9:0.9: 0.9 How else can you customize colors in Ubuntu 18.04? My options are: lspci | grep -E "VGA|3D" 01:00.0 VGA compatible controller: NVIDIA Corporation GK208B [GeForce GT 710] (rev a1) sudo lshw -c display |grep driver

Answer 1

1) Isn't it easier to set up a monitor?
2) Create two profiles, one for light theme and one for dark.
3) If it starts to turn yellow when the brightness/contrast decreases,
then select the RGB gamma/balance more precisely (you have -g 0.9:0.9:0.9 - this is 1:1
, for example, try -g 0.9:0.91:0. 956
man redshift
Gamma value must be between 0.1 and 10.0.
