Pale almost transparent growth?

[goodsmeagol]

I recently got a new Russian Female YEY
Many have been great in another thread and have not mentioned the growth rings I am referring to here so I do not believe it to be a huge concern.
However, there is a section of growth, what I would guess is the growth she experienced under her last owner that appears pale and almost translucentish.

I am wondering what causes this, or if I need to do anything about it.
Sections above the hind feet bubble out slightly moreso then normal growth rings should I think.
Thanks

It really doesn't look concerning. I bet with some good sunshine and time it will darken.

Like Matt said nothing to worry about as thats very normal. All new growth is lighter colored and darkens with age and sun exposure.
