                     Text="{x:Bind Name, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
                     Foreground="{x:Bind NameErrorsList.Count, 
                                         Mode=OneWay,

                                         Mode=OneWay, 
                                         Converter={StaticResource ErrorListToForegroundConverter}}"/>

My textbox is not turn back to default foreground when being input or focus When lose focus and refocus again I apply the default foreground I think the problem is in here 
return errorCount != 0 ? new SolidColorBrush(Colors.Yellow) : null
return errorCount != 0 ? new SolidColorBrush(Colors.Yellow) : null
when change the null to new SolidColorBrush(Colors.Green) It react and turn green even when being focus does anyone know how to set the textbox foreground back to default color using C# ?
