Custom Control Entry not getting set the Place Holder Color Bindable Property

Question

I have a custom control its a date picker but the PlaceHolderColor is not being set and not having affect.

public Color PlaceHolderColorText
{
     get => 
     (Color)GetValue(PlaceHolderColorProperty);
     set => SetValue(PlaceHolderColorProperty,
     value);
}

 public static readonly BindableProperty
 PlaceHolderColorProperty = 
BindableProperty.Create(nameof(PlaceHolderColor), 
typeof(Color), 
typeof(DateTimePicker2),Color.Black , BindingMode.TwoWay, 
 propertyChanged: OnPlaceHodlerColorChanged);

I am creating dynamic entrys as such

public Entry _dayEntry { get; private set; } = new Entry() { 
TabIndex = 0, Placeholder = "dd", Keyboard = Keyboard.Numeric, 
WidthRequest = 60, HorizontalOptions = LayoutOptions.Start };
 
public Entry _monthEntry { get; private set; } = new Entry() { 
TabIndex = 1, Placeholder = "MM", Keyboard = Keyboard.Numeric, 
WidthRequest = 60, HorizontalOptions = LayoutOptions.Start };
  

But I am unsure as to what I need here to get the value to apply to the entry properly

public static void OnPlaceHodlerColorChanged(BindableObject 
bindable, object oldValue, object newValue)
{
        var test = newValue;      
     ///do something with new but dont no what.
}

I am adding my entrys like this to the children of the stack

public DateTimePicker2()
{
    BindingContext = this;

    _dayEntry.TextChanged += _dayEntry_TextChanged;
    _monthEntry.TextChanged += _monthEntry_TextChanged;
    _yearEntry.TextChanged += _yearEntry_TextChanged;
    _dayEntry.TextColor= TextColor;
    _monthEntry.TextColor= TextColor;
    _yearEntry.TextColor= TextColor;
    _dayEntry.PlaceholderColor = PlaceHolderColor;
    _monthEntry.PlaceholderColor = PlaceHolderColor;
    _yearEntry.PlaceholderColor = PlaceHolderColor;
    _hourEntry.TextColor= TextColor;
    _minsEntry.TextColor= TextColor;
    SelectedDateChanged +=DateTimePicker2_SelectedDateChanged;
    Content = new StackLayout()
    {
        Orientation = StackOrientation.Horizontal,
            Children =
            {    _datePicker,
                 _timePicker,
                _monthEntry,
                _dayEntry,                    
                _yearEntry,
                _hourEntry,
                _minsEntry,
                _ampmPicker,
                iconButton

 }
};

I am a bit perplexed as to what to do to get the event to register the place holder color to correct entry you will see am doing here.

_dayEntry.PlaceholderColor = PlaceHolderColor;

Thanks in advance
