Highlight current tab

Is there anyway to highlight the currently selected tab ?
I use the i3 window manager, and I cannot distinguish between the current tab and any other tab in a KDE konsole window.
Thanks

Konsole looks like this for me:

I think this is driven by the “Application Style” selected in the KDE settings because the preview there shows precisely this blue bar and those background colors

You could use a specified css style sheet.
Create pne like, for example:

QTabBar::tab {
color: #8aa4b7;
background-color: #26292c;
font-size: 12px;
height: 25px;
padding: 0px;
border: 0px;
min-width: 120px;
max-width: 120px;
}
QTabBar::tab:selected {
background-color: #0088cc;
color: #ffffff;
}
QTabBar::tab:hover {
background-color: #ff5500;
color: #FFFFFF;
}

This one looks like:

Btw, I forgot to mention that you can change the entire tabbar panel color if you like.
See the last lines ( check the bright yellow #e7c00b example)

QTabBar::tab {
color: #0088ff;
background-color: #26292c;
font-size: 12px;
height: 25px;
padding: 0px;
border: 0px;
min-width: 120px;
max-width: 120px;
}
QTabBar::tab:selected {
background-color: #0088cc;
color: #ffffff;
}
QTabBar::tab:hover {
background-color: #ff5500;
color: #FFFFFF;
}

QWidget, QTabWidget::pane, QTabWidget::tab-bar {
background-color: #e7c00b;
}

You can also launch konsole with predefined tabs ( konsole --tabs-from-file).
But I don’t know if you can assign a colorcode for each predefined tab.
