It turns out the problem was caused that the logic in MaterialEntryRenderer.

Find the method SetPlaceholderColor , it changes the placeholderColr rendering.

Modify it as below:

private void SetPlaceholderColor()
{
    if (Element.PlaceholderColor == Color.Default)
    {
        Control.FloatingLabelTextColor = _defaultPlaceholderColor;
        Control.AttributedPlaceholder = new NSAttributedString(Control.Placeholder, new UIStringAttributes { ForegroundColor = _defaultPlaceholderColor });
    }
    else {
        Control.FloatingLabelTextColor = Element.PlaceholderColor.ToUIColor();
        Control.AttributedPlaceholder = new NSAttributedString(Control.Placeholder, new UIStringAttributes { ForegroundColor = Element.PlaceholderColor.ToUIColor() });
    }
}

Then you can change the placeholder color as you want .

var userNameEntry = new Entry()
{
    Placeholder = "UserName",
    PlaceholderColor = Color.Red,
    TextColor = Color.Green,
};

var passwordEntry = new Entry()
{
    Placeholder = "Password",
    PlaceholderColor = Color.Black,
    TextColor = Color.Gray,
};
