Well, all of the text from WinMo is usually white by default. If you are seeing black text then that may be text generated by or part of something else that is installed like your easy today launcher.
I have no clue if you can change font colors within for those apps.
If you are using the standard WinMo Today screen with add-ons then I think you can change colors on just about everything with the UI-Tweaker app. Here is a link to UI-Tweaker:
