After run the application type person Id in textbox (for example 1) and press the change color button, the color will change but the listbox dose not respond for that change.

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));
    }
}
