This is how you can change the color of Action Bar.

import android.app.Activity;
import android.content.Context;
import android.graphics.Color;
import android.graphics.drawable.ColorDrawable;
import android.os.Build;
import android.support.v4.content.ContextCompat;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;


public class ActivityUtils {

public static void setActionBarColor(AppCompatActivity appCompatActivity, int colorId){
    ActionBar actionBar = appCompatActivity.getSupportActionBar();
    ColorDrawable colorDrawable = new ColorDrawable(getColor(appCompatActivity, colorId));
    actionBar.setBackgroundDrawable(colorDrawable);
}

public static final int getColor(Context context, int id) {
    final int version = Build.VERSION.SDK_INT;
    if (version >= 23) {
        return ContextCompat.getColor(context, id);
    } else {
        return context.getResources().getColor(id);
    }
}
}

From your MainActivity.java change the action bar color like this

    ActivityUtils.setActionBarColor(this, R.color.green_00c1c1);
