Eclipse luna dark theme with openSUSE13.1

Hi everyone,
I instal fresh openSUSE13.1 and eclipse luna
After that, I switch eclipse to dark theme as: Windows > Preferences > General > Appearance > Theme > Dark

Everything is good except I can’t see text on button (backgound is grey and text color is white, too hard for my eye)
Sorry I can’t upload image to any web because of my company’s proxy

How do I solve it? Thank you

PS: I try dark theme eclipse on Gnome (redhat) and it’s okay
