Problem with difference in color of Android app. Android Studio appears one way and my phone is totally different

Question

Hello, all right? I’m starting now in Mobile Development. My problem is the following:

I created a simple app for testing, in Android Studio it gets the colors the right way I want, but when I install it on my phone, yellow gets a negative effect and the color is almost black instead of yellow. I’m having trouble solving it. The whole project was created by the IDE and I just modified it... The Styles file didn’t exist, so I created one from scratch. Follow him down:

<?xml version="1.0" encoding="utf-8"?>


<resources>
    <style name="AppTheme" >

    <!-- Create your theme here-->
        <item name="colorPrimary">@color/white</item>


    </style>
    
    <style name="Operators_Button">
        <item name="android:layout_width">0dp</item>
        <item name="android:layout_height">match_parent</item>
        <item name="android:layout_weight">1</item>
        <item name="android:background">@color/orange_red</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:textSize">28dp</item>
        <item name="android:gravity">center</item>
        <item name="android:textStyle">bold</item>
        <item name="android:layout_margin">0.5dp</item>
    </style>
    
    <style name="Numbers_Button">
        <item name="android:layout_width">0dp</item>
        <item name="android:layout_height">match_parent</item>
        <item name="android:layout_weight">1</item>
        <item name="android:background">@color/yellow</item>
        <item name="android:textColor">@color/black</item>
        <item name="android:textSize">28dp</item>
        <item name="android:gravity">center</item>
        <item name="android:textStyle">bold</item>
        <item name="android:layout_margin">0.5dp</item>
    </style>

Answer 1

I realized my phone was in Dark mode, deactivated and the colors were normal as I expected. The question now is to understand how to make my app not be modified by the "dark mode" option of the phone.
