Use a style sheet to change the selected tab color:

/* Change the selected tab's background to a light gray */
QTabBar::tab:selected {
     background: #999999
}

/* Change the selected tab's text to red */
QTabBar::tab:selected {
     color: red
}

These examples come from the Konsole help, chapter 6 "Using Style Sheet for the Tab 
Bar" available from Help -> "Konsole Handbook". There are other examples there as well.

The only thing not explicitly mentioned in my copy of this page is that one sets 
their stylesheet file in Settings -> "Configure Konsole" -> "Tab Bar" -> "Use 
user-defined stylesheet:".
