F12: GTK horrible selected item contrast

[Tom Horsley]

I've gotten most things working on F12 now, but I'm seeing
this horrible looking contrast on selected items or text
in all GTK apps. Sort of a medium blue-gray background
with white text foreground.

Is this they way GTK looks these days, or is something
horrible leftover in my home directory influencing the
appearance?

(I guess I should go make a new user from scratch and
see what his GTK apps look like).
