how to add system colors

how to add system colors in a combo box when the form is loaded in VB or C# or VB.net. if the color is clicked the font color should be changed?

Here is the code in VB.NET to load the color in combobox

Dim asm As [Assembly] ' Assembly is reserved vb word so use the brackets to override
Dim myClasses() As Type
Dim myProperties() As PropertyInfo

Dim myTypeInfo As Type
Dim myPropertyInfo As PropertyInfo

' Lets load the System.Drawing dll
asm = [Assembly].LoadWithPartialName("System.Drawing")
If Not (asm Is Nothing) Then
' get an array of base classes
myClasses = asm.GetTypes()
End If

' Loop through each class
For Each myTypeInfo In myClasses
' if it is the color class
If myTypeInfo.ToString() = "System.Drawing.Color" Then
' get an array of all the properties
myProperties = myTypeInfo.GetProperties()
' loop the properties
For Each myPropertyInfo In myProperties
' if the property returns a Color object, then lets output it
' to the console as their are some non color properties we
' dont want to list
If myPropertyInfo.PropertyType.ToString() = "System.Drawing.Color" Then
ComboBox1.Items.Add(myPropertyInfo.Name)
End If
Next myPropertyInfo
End If
Next myTypeInfo
