You should implement INotifyPropertyChanged interface also in People class:

public class People : INotifyPropertyChanged
{
    public int PersonID { get; set; }

    private string _fullName;
    public string FullName
    {
        get { return _fullName; }
        set { _fullName = value; OnPropertyChanged("FullName"); }
    }

    private bool _Status;
    public bool Status
    {
        get { return _Status; }
        set { _Status = value; OnPropertyChanged("Status"); }
    }

    private SolidColorBrush _statusColor;
    public SolidColorBrush StatusColor
    {
        get { return _statusColor; }
        set { _statusColor = value; OnPropertyChanged("StatusColor"); }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void OnPropertyChanged(string name)
    {
        if (PropertyChanged != null)
            PropertyChanged(this, new PropertyChangedEventArgs(name));
    }
}
