Can't find the function of these properties

[DanteAndroid]

<!--
        <item name="colorControlNormal">@color/iron</item>
        <item name="colorControlActivated">@color/white</item>
        <item name="colorControlHighlight">@color/primary</item>
        <item name="android:textColorHint">@color/iron</item>

        <item name="colorButtonNormal">@color/primary_darker</item>
        <item name="android:colorButtonNormal">@color/primary_darker</item>
        -->

In styles.xml, I commented these, just to get the same effect. (on Android 5.1)
