Well, I'm trying to use a theme, so please can somebody answer the question for me?

I don't think that the shadowing code path can be avoided just by using
a RC style.   And while GdkPango defines a text attribute for the emboss
color (which is indeed white by default), I can't see how you could
influence it.

So, you can probably write a theme engine, but I might try a sneaky way
first: subclass GtkStyle, override just draw_layout() method with the
code taken from gtk_default_draw_layout() with the insensitive layout
code deleted (which will make the function trivial), and then
instantiate this style and set it on your labels.  I haven't tried it
and, of course, it will interact badly with theme engines but
interaction with theme engines probably isn't something you care about
with such requirements...
