Pink streaks in P . Pine ? I dont remember that. We used to train with P. Pine at Tae Kwondo, because when you punch / kick it (properly) it makes a clean split with no splinters, but i never saw pink streaks, but happy to be wrong, if i am.
The wood in the OP does look like Pine , but then it looks like a lot of similar light coloured woods, looking at the grain/colour
