Use android:colorPrimary. colorPrimary on its own will only work if you are inheriting from Theme.AppCompat.

So, for example, in this sample project, I have:

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <style name="Theme.Apptheme" parent="android:Theme.Material">
    <item name="android:colorPrimary">@color/primary</item>
    <item name="android:colorPrimaryDark">@color/primary_dark</item>
    <item name="android:colorAccent">@color/accent</item>
  </style>
</resources>
