Yes, this is the property you are looking for: buttonTint, but only works at api level 21 or higher
<RadioButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/radio" android:checked="true" android:buttonTint="@color/your_color"/>
in your /colors.xml values put your color in this case reddish:
<color name="your_color">#e75748</color>
Result:
