Color doesn't work

Hello. I can’t change slide background color i have tried AppIntro and AppIntro2 My code:

public class MyIntro extends AppIntro {
    @Override
    public void init(Bundle savedInstanceState) {
        addSlide(AppIntroFragment.newInstance(getString(R.string.intro_title_main)
                , getString(R.string.intro_description_main), R.drawable.intro_image_main
                , R.color.colorAccent));
        showDoneButton(true);
        setFlowAnimation();
    }

where R.color.colorAccent is light blue

<color name="colorAccent">#2480b3</color>

manifest

<activity
            android:name=".activity.MyIntro"
            android:label="@string/app_name"
            android:theme="@style/Intro">

styles

<style name="Intro" parent="Theme.AppCompat.NoActionBar">
</style>

and the result:

Or you may just be using this : ContextCompat.getColor(this, R.color.primaryColor)

@Toubap ContextCompat.getColor(this, R.color.primaryColor) seemed to work for me
