Selector for a tab with unread data

[fedon]

I use css style to distinguish tabs in Konsole application:

QTabBar::tab:selected {
  background: #4286f4
}
QTabBar::tab:hover {
  background: #dff442
}
QTabBar::tab:selected:hover {
  background: #fd4442
}
QTabBar::tab {
  background: #449449
}

QTabBar::tab:selected {
  background: #4286f4
}
QTabBar::tab:hover {
  background: #dff442
}
QTabBar::tab:selected:hover {
  background: #fd4442
}
QTabBar::tab {
  background: #449449
}

To copy to clipboard, switch view to plain text mode 

Everything works fine. The only problem I can not solve is foreground for a tab which has unread data. Does anyone know which selector to use? Default style conflicts with my color.
