Are you using QListView with a model, or a QListWidget?
In both cases you have to set the font in the item, not the list.
See QListWidgetItem.

You can change font color form Style Sheet .

i tried to do it by using HTML Markup but it didn't work .. it seems like it only work with text Widgets.

i don't think it is possible to change a single item color in list view.

You can create custom QListWidgetItem and use a "index-based" color.

class ColouredItem : QListWidgetItem
{
private:
    static const int numberOfColors = 3;
    static QColor ColouredItem::colorList[numberOfColors];
 
public:
    void updateItemColor()
    {
        int row = this->listWidget()->row(this);
        this->setForeground(QBrush(colorList[row % numberOfColors]));
    }
}
 
QColor ColouredItem::colorList[numberOfColors] = {QColor::fromRGB(255, 0, 0), QColor::fromRGB(0, 255, 0), QColor::fromRGB(0, 0, 255)};

class ColouredItem : QListWidgetItem
{
private:
    static const int numberOfColors = 3;
    static QColor ColouredItem::colorList[numberOfColors];

public:
    void updateItemColor()
    {
        int row = this->listWidget()->row(this);
        this->setForeground(QBrush(colorList[row % numberOfColors]));
    }
}

QColor ColouredItem::colorList[numberOfColors] = {QColor::fromRGB(255, 0, 0), QColor::fromRGB(0, 255, 0), QColor::fromRGB(0, 0, 255)};

To copy to clipboard, switch view to plain text mode 

When you need to update the color just call that updateItemColor function.

If you need a "type-based color". Just change the colorList[row % 3] to get color based on type or something else.
