Active-Tab-Color
This property allows you to set or retrieve the color of the active tab in a Tab-Control control. Foreground and background color values are combined and therefore RGB colors are not supported. See "Color management" for further details.
This property affects only Tab-Controls with the Accordion style and Tab-Controls with the Tab-Flat style.
 
Example - Define a tab-control with foreground and background colors for the active tab
screen section.
