How to make a drop-down list of flowers in WPF?

Need a drop-down list that will display only the color.

<ComboBox Grid.Row="11" Grid.Column="2" Width="Auto" Height="Auto" MinWidth="100" VerticalAlignment="Bottom" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding ColorList}" SelectedIndex="{Binding ColorSelect}" SelectedValue="{Binding ColorSelectValue}" SelectedValuePath="Id" Text="variable"> <ComboBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Rectangle Width="16" Height="16" Margin="0,2,5,2" Fill="{Binding Name}" /> <TextBlock Text="{Binding Name}" /> </StackPanel> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> 

Viewmodel

 private void GetColorId() { ColorCollection.Add(new ColorsServices(0, Colors.Black)); ColorCollection.Add(new ColorsServices(1, Colors.Yellow)); ColorCollection.Add(new ColorsServices(2, Colors.Green)); ColorCollection.Add(new ColorsServices(3, Colors.Gray)); ColorCollection.Add(new ColorsServices(4, Colors.PaleGreen)); ColorCollection.Add(new ColorsServices(5, Colors.Violet)); ColorCollection.Add(new ColorsServices(6, Colors.CadetBlue)); } private ObservableCollection<ColorsServices> ColorCollection = new ObservableCollection<ColorsServices>(); 

and Service

 public class ColorsServices { public ColorsServices(int id, Color name) { Id = id; Name = name; } public int Id { get; set; } public Color Name { get; set; } } public ObservableCollection<ColorsServices> ColorList { get { return ColorCollection; } set { ColorCollection = value; } }
