Textblock style binding

I want to change a textblock color or style in code with a Viewmodel binding. This is what I got:

<TextBlock 
     Visibility="{Binding SubTitleVisibility}" 
     Text="{Binding SubTitle1}" 
     TextWrapping="Wrap" 
     Margin="12,-6,12,0" 
     Style="{Binding SubColor}"/>

Every binding works here except for the style. Though it applies the font size but without a color. (As Queen would say it's a kind of magic)

View model:

    internal DisplayMode Mode
    {
        get
        {
            return _mode;
        }
        set
        {
            //if (value != _type)
            //{
            _mode = value;
            if (value.Equals(DisplayMode.EditMode) && _type.Equals(ItemType.WithIcon))
            {
                _iconVisibility = Visibility.Visible;
                SubTitleVisibility = Visibility.Collapsed;
            }
            else if (_type.Equals(ItemType.WithSubTitle))
            {
                _iconVisibility = Visibility.Collapsed;
                SubTitleVisibility = Visibility.Visible;
            }

            NotifyPropertyChanged("Mode");
            NotifyPropertyChanged("SubColor");
        }
    }

    internal Style SubColor
    {
        get
        {
            Style temp; 
            if (_group != "phone" && _group != "email" && _mode == DisplayMode.ViewMode)
                temp = (Style)App.Current.Resources["PhoneTextNormalStyle"];
            else
                temp = (Style)App.Current.Resources["PhoneTextAccentStyle"];

            return temp;
        }
    }

I found this codesnippet here, but it won't even go into the get method of the SubColor.

Thanks in advance for your help.

Your approach is wrong. You shouldn't attempt to bind a style to your ViewModel, but instead use a Data Template Selector.
