The example below cancels the value changing if the new value is not a named color:

Cancel ValueChanging.

private void radColorBox1_ValueChanging(object sender, Telerik.WinControls.UI.ValueChangingEventArgs e)
    e.Cancel = !((Color)e.NewValue).IsNamedColor;

Private Sub RadColorBox1_ValueChanging(sender As Object, e As Telerik.WinControls.UI.ValueChangingEventArgs)
    e.Cancel = Not DirectCast(e.NewValue, System.Drawing.Color).IsNamedColor
End Sub
