Placing icons to action bar

Question

I am placing icons to action bar. It looks like this:

Why search icon is more white? I want to do same color with setting icon. How can I do this?

My xml:

<item android:id="@+id/action_favorites"
      android:icon="@drawable/ic_search"
      android:title="Takip Listesi"
      android:showAsAction="always" />

<item android:id="@+id/action_settings"
      android:icon="@drawable/ic_action_settings"
      android:title="Settings"
      android:showAsAction="always" />
