I have a problem with color rendering in Evince (3.18.2) in Ubuntu 16.04: the colors are darker than normal since a few days. Below a picture that shows a pdf file rendering in Okular on the left (correct) and in Evince on the right (too dark).
Is there a way to tune or to reset the color scheme of Evince ?
EDIT: I have the same problem with EyeOfGnome when opening image file. May be the problem relates to gnome. Still trying to find an explanation.
EDIT2: The problem seems related to gnome apps and several users seem to try to solve it (such as (Unity desktop) My applications became darker for unknown reason or Why have colors suddenly become dark and saturated in Gtk3 features & applications on my GNOME system?).
