New gtk-2.0 theme in KDE

[Jonathan Ryshpan]

When evolution is run under KDE the color scheme is not good; the color
of the selected message is barely different from that of unselected
messages.  Various themes (available from System Settings->Application
Appearance->GTK+ Appearance) produce various color schemes.  The one I
like best is Adwaita, whose color scheme I like but whose widgets are
less attractive than the ones in the default theme oxygen-gtk.  So...

I copied the oxygen-gtk theme into my local folder (~/.local), where GTK
+ Appearance finds it and edited gtkrc to look like Adwaita's so far as
colors go.  The key part of the edited file appears at the bottom of
this posting.  I enabled it using GTK+ Appearance; unfortunately there's
no change in the color scheme.  What have I done wrong?
