Hello David,
Currently, I have not found a way to set the label text color on a Easy Tab control. The 5 attributes you can set for a tab of a tab control are Tab Visible, Tab Dimmed, Tab Label Text, Tab Label Background Color, and Tab Color.
If you are want to highlight a tab when it is active, you might consider either dimming all the other tabs so that the active one stand out, or changing the background color of the active tab.
I hope this helps.
