How do I change background in TextInputLayout in xml?

Question

android studio

This style has the default gray color for the stroke of this box and the triangle.
I want to change their colors to blue.

<com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="@dimen/margin10"
            style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu">

            <AutoCompleteTextView
                android:id="@+id/cropsAuto"
                android:textSize="@dimen/text_size"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:inputType="none"
                android:text="@string/choose_one_of_them" />

How can I do it ?
