Why can't I change the color of the button?

Question

Android

Previously, by specifying background black on the view, you could change the color (for example, buttons). It could also be done via style. Now it doesn't work for some reason.
I have an idea that this is due to the update of android studio and the appearance of the themes folder in the values. Maybe I'm wrong
Who knows what's wrong. Tell me plz.

<com.google.android.material.button.MaterialButton
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:layout_marginEnd="@dimen/margin_button"
            android:layout_marginStart="@dimen/margin_button"
            android:layout_marginBottom="@dimen/margin_button"
            android:background="@color/coral"
            />

<style name="Theme.Smoke" parent="Theme.MaterialComponents.DayNight.NoActionBar">
        <item name="colorPrimary">@color/white</item>
        <item name="colorPrimaryVariant">@color/coral</item>
        <item name="colorOnPrimary">@color/white</item>
        <item name="colorSecondary">@color/teal_200</item>
        <item name="colorSecondaryVariant">@color/teal_700</item>
        <item name="colorOnSecondary">@color/black</item>
        <item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
        <item name="buttonBarStyle">@color/coral</item>
        <item name="android:buttonStyle">@color/coral</item>
    </style>

    <style name="SplashScreenTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
        <item name="android:windowBackground">@drawable/splash_image</item>
    </style>

    <style name="ThemeOverlay.Smoke.FullscreenContainer" parent="">
        <item name="fullscreenBackgroundColor">@color/light_blue_600</item>
        <item name="fullscreenTextColor">@color/light_blue_A200</item>
    </style>
