I am sorry 😞 you are dealing with this. I used Natural Seal and Traffic HD on white oak and my floors are not pink for sure. I noticed that in my master closet by mistake was installed red oak plank and it definitely has pinkish undertone so maybe You are right that you had red oak installed. I think they are some tests to check it. Here is my white oak floors with Bona Natural Seal and Traffic HD.
