```
import QtQuick 2.13
import org.kde.plasma.components 3.0 as PlasmaComponents
import org.kde.plasma.core 2.0 as PlasmaCore
PlasmaCore.ColorScope {
//colorGroup: PlasmaCore.Theme.ComplementaryColorGroup
Rectangle {
height: 80
width: 100
color: "red"
PlasmaComponents.ToolButton{
anchors.fill: parent
text: "sup"
}
}
}
```
The label was white instead of black.
