Comment 1 for bug 1408643

Currently we have this in MainView.qml:

            dividerColor: Qt.darker(background.headerColor, 1.1)
            panelColor: Qt.lighter(background.headerColor, 1.1)

I propose, as Michael said, to use a "darkness threshold" and if the color is too dark, use dividerColor: Qt.lighter(...) instead of Qt.darker().

Ideally we should also make all the color properties available so that they can be change din the header style.
