Bug 401576: kwin rules for app-specific color themes: facilitate color matching
between titlebar and app color
https://bugs.kde.org/show_bug.cgi?id=401576



--- Description ---
The current way to get color matching between app color and title-bar color is
tedious for users (especially since GTK apps don't follow KDE color schemes). I
am wondering if it could be done in a way that requires less user input

Some ideas:
1. (KWin feature, invasive, lots of work for developers) A script polls (or
examines at first launch) the color under the title-bar - usually in the upper
left corner - and sets the appropriate titlebar color, maybe with some user
input if at first launch.

2. (KCM, user-input) Setting to change the titlebar color only without having
to create a new color scheme. The complementary color values for
active/inactive text should be automatically generated based on the the chosen
app-specific tile-bar colors and the based on the contrast values implied by
the global color scheme.
