just noticed that in Qt 5.7 there's a new property Material.foreground:
http://doc-snapshots.qt.io/qt5-5.7/qtquickcontrols2-material.html#foreground-attached-prop
seems this didn't make it into the 5.7 Beta
from docs:
The default value is theme-specific (light or dark).
So there's no dependency between primary and foreground and I have to calculate it by myself for text inside ToolBar

still my question about tinting images for Material

it's really easy to create a Toolbar with Title and Menu using qt.labs.controls and Material style:

import QtQuick 2.6
import QtQuick.Layouts 1.3
import Qt.labs.controls 1.0
import Qt.labs.controls.material 1.0

ToolBar {
    id: titleToolBar
    property alias text: titleLabel.text
    RowLayout {
        focus: false
        spacing: 20
        anchors.fill: parent
        Label {
            id: titleLabel
            text: "ekke"
            font.pixelSize: 20
            elide: Label.ElideRight
            horizontalAlignment: Qt.AlignHCenter
            verticalAlignment: Qt.AlignVCenter
            Layout.fillWidth: true
        }
        ToolButton {
            Image {
                anchors.centerIn: parent
                source: "qrc:/images/menu.png"
            }
            // onClicked: doSomething()
        }
    }
}

I'm getting the primaryColor as background of ToolBar as expected.

Problem is when primaryColor is a dark color and needs white as text color.

Here's the overview of Material Color Palette where you can see when text should be black or white:

http://www.google.com/design/spec/style/color.html#color-color-palette

I'm always getting black as color - is there something like color: Material.textOnPrimary ?

Or do I have to handle this by my own logic or mappings ?

Using a dark primary color not only needs white text color, but also white Images as used in ToolButton -> Image above.

Hi,

The latest 5.7 branch now has the correct ToolBar foreground color out of the box, when using one of the pre-defined primary colors.
