For color-sensitive work, the Color Profiles settings dialog allows you to install and manage color profiles for your displays, printers, and scanners. In order for color profiles to be used, the required daemon will need to be installed and running in the background:
xiccd for display profiles
cupsd for printer profiles
saned for scanner profiles
To calibrate your display, you will need to install DisplayCAL, GNOME Color Manager (gnome-color-manager) with a ColorHug device, or a similar tool. If you would like to add
a “night-mode” or “blue-blocker” feature, that will automatically
transition the color temperature of the display throughout the day, you can install RedShift (redshift).
