Under KDE on OpenSUSE Tumbleweed Emacs gets default colours from
my Desktop Environment settings.

I have also noticed that if I define background, foreground, as well as
color0, color1,..., color15 in my .Xresources file Emacs prefers those settings
over my DE settings.

I have noticed there are users who are unfortunately stuck on Apple's MacOS, I
think they may have issues setting a colour scheme (I once had a job where
MacOS Yosemite was required, I couldn't find a way to change theming settings).

As for Microsoft Windows, I unfortunately don't know if it has any sort of
standard for theming settings.
