Colors in ProUIDialog

Does anyone know if its possible to change the color of text (or a pushbutton) in Toolkit's ProUIDialog or ProUILayout functions? Basically I'm looking to change the color of text inside a button, to show it in red, but all my attempts to use ProTextColorModify() seem to be failing. I only see Foreground and background options for the Drawing box, and I'd like to avoid that if possible.

Thanks,

Sully
