It is hard to be certain from looking at the pictures, but I would lean toward white oak from the first image. Here is an article that may help. https://www.wood-database.com/wood-articles/distinguishing-red-oak-from-white-oak/

closer look

what throws me off is it looks like there's a reddish tint to it but maybe that's coming from the paper 🤷‍♂️

I don't see any medullary rays that look to be longer than 1" so I'd say it's Red Oak.

The graining appears to me to be more like red then white oak as well.
