To change the selected tab icon color in BottomNavigationView you should use the Selector.

Create bottom_navigation_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_checked="true" android:color="@color/yourSelectedColor" />
  <item android:color="@color/defaultColor"  />
</selector>

Apply app:itemIconTint="@drawable/bottom_navigation_selector" to your BottomNavigationView in xml file.
