Is there a way to change the colors of inactive menu items?

Hello,
I have changed my KDE apearance for an almost black background.
In LO (writer or calc), it does not seem to change everything (as could be expected for non-KDE applications).
One pb remains. The inactive links in the menu are black on almost black.
Is there a way to change the colors of inactive links somewhere in the LO parameters or something else ?
