Hi Kostya...
the client already rejected my previous approach which involved inspecting
a drawable.
I've finally given them the option of either using ActionBarSherlock and
forcing the use of the overflow menu or developing some custom icons that
will work with both a white or black option menu background. I mocked up
some samples today using their existing custom icon on top of a white
rounded rectangle and they actually look quite good.
Thanks very much for the help and advice though - much appreciated.
Nick
