how to change material TextInputLayout hint color on empty edittext?

Question

I'm trying to change TextInputLayout hint color in case it's edittext empty and not focused but I can't do that, and here is my layout

<com.google.android.material.textfield.TextInputLayout
                        android:id="@+id/input_layout"
                        style="@style/text_material_input_hint_neutral_80_normal"
                        android:layout_width="0dp"
                        android:layout_height="wrap_content"
                        android:layout_marginStart="17dp"
                        android:layout_marginTop="26dp"
                        android:layout_marginEnd="17dp"
                        android:layout_marginBottom="24dp"
                        android:hint="@string/store_url"
                        android:textColorHint="@color/neutral_80"
                        app:boxBackgroundColor="@color/neutral_10"
                        app:boxCornerRadiusBottomEnd="8dp"
                        app:boxCornerRadiusBottomStart="8dp"
                        app:boxCornerRadiusTopEnd="8dp"
                        app:boxCornerRadiusTopStart="8dp"
                        app:boxStrokeWidth="0dp"
                        app:boxStrokeWidthFocused="0dp"
                        app:hintTextColor="@color/neutral_80"
                        app:layout_constraintBottom_toBottomOf="parent"
                        app:layout_constraintEnd_toEndOf="parent"
                        app:layout_constraintStart_toStartOf="parent"
                        app:layout_constraintTop_toTopOf="parent">


                        <com.google.android.material.textfield.TextInputEditText
                            android:id="@+id/edittext"
                            style="@style/text_material_input_text_neutral_130_normal"
                            android:layout_width="match_parent"
                            android:layout_height="wrap_content"
                            android:maxLines="1"
                            android:text="test string"
                            android:paddingStart="12dp"
                            android:paddingTop="24dp"
                            android:textAlignment="viewStart" />

                    </com.google.android.material.textfield.TextInputLayout>

and here is my used styles

  <style name="text_material_input_hint_neutral_80_normal" parent="TextAppearance.AppCompat">
        <item name="android:textSize">12sp</item>
        <item name="android:textAllCaps">false</item>
        <item name="android:includeFontPadding">false</item>
        <item name="android:textColor">@color/neutral_80</item>
    </style>

    <style name="text_material_input_text_neutral_130_normal" parent="TextAppearance.AppCompat">
        <item name="android:textSize">14sp</item>
        <item name="android:colorAccent">@color/secondary_80</item>
        <item name="android:textAllCaps">false</item>
        <item name="android:includeFontPadding">false</item>
        <item name="android:textColor">@color/neutral_130</item>
        <item name="colorControlActivated">@color/secondary_80</item>

    </style>

I'm using colorControlActivated as some answers suggests on similar case and also android:colorAccent but that's not help?

How can I apply a different hint color in case the edit text is empty and not focused?

Order of calling function is really important.

binding.txtLoginInputLayout.apply {
            defaultHintTextColor = ContextCompat.getColorStateList(context, R.color.blue)
            hintTextColor = ContextCompat.getColorStateList(context, R.color.red)
        } 

  binding.edtLoginInputLayout.apply {
            setTextColor(
                ContextCompat.getColorStateList(
                    context,
                    R.color.green
                )
            )

            highlightColor = ContextCompat.getColor(context, R.color.green_light)
        }
