You don’t. All you do is ask for a Tab style button: protected final AquaPainter<JRSUIState> painter = AquaPainter.create(JRSUIStateFactory.getTab()); It's a nice abstract interface, but it lacks the corresponding API for getting the Tab text color to match a given appearance and state. Basically, the API is incomplete and has not been kept up to date. Otherwise, VAqua would not exist. :-)
