[Inkscape-user] white tooltip text is hard to read

Is there a way to change the color of the tooltip text? Now it's white on gray and hard to see. I don't see anything in ~/.config/inkscape/preferences.xml that allows this to be changed. Black on gray would be nice.

Specifically where this came up is in the magnify context. Fit selection, drawing and page icons are the same. Tooltips are needed to distinguish the action associated with each icon.

Thank you Carl
