Well, seems you're using Oxygen theme and black fonts.
Open up systemsettings (KDE control center), go to Appearance, then Workspace Design
(or Desktop Design, don't know what it's called in english) and choose another theme you like.
If that still doesn't suit you, then from systemsettings, go to Appearance of Programs,
and select fonts and colors and styles you like.
