How to set support library snackbar text color to something other than android:textColor?

I found this at What are the new features of Android Design Support Library and how to use its Snackbar?

This worked for me for changing the text color in a Snackbar.

Snackbar snack = Snackbar.make(view, R.string.message, Snackbar.LENGTH_LONG);
View view = snack.getView();
TextView tv = (TextView) view.findViewById(android.support.design.R.id.snackbar_text);
tv.setTextColor(Color.WHITE);
snack.show();

UPDATE: ANDROIDX:
As dblackker points out in the comments, with the new AndroidX support library, code to find the ID of Snackbar TextView changes to:

TextView tv = view.findViewById(com.google.android.material.R.id.snackbar_text);
tv.setTextColor(ContextCompat.getColor(requireContext(), R.color.someColor))
