I just updated my Nexus4 from Kitkat to Lollipop. The most obvious change for me is the background color of the theme and especially the keyboard. It used to have a black background, now its color is the brightest of whites hurting my poor eyes. Can I change the background color back into blackness, and if so, how?
Note: I like to avoid keyboard apps from third parties. I know they exist in different flavors, but I like to keep it native.
